2) I noticed the Rimward expedition isn't posted, but the Zhodani coreward expedition is; was there reason for that?
A not-so-brief history:
In the 1990s, Bari Z. Stafford (a.k.a. General Turokan) designed a series of sectors leading from Charted Space trailing-rimward to the rim of the Galaxy, as well as associated library data and "log reports" detailing about the expedition.
Later on, Clifford Linehan charted out the Zhodani Core Route mentioned in the Traveller canon. He interviewed Marc Miller for details and incorporated these into the route. For a time, Clifford hosted both details about his
Core Route sectors and Bari's Rim Route sectors on his site.
Bari passed away in 2002. I started up travellermap.com in 2005. As I was populating the site, I came across Clifford's site, and asked for permission to incorporate his Core Route sectors, which was granted. A few years later, Clifford's site host (Geocities) was shut down.
At the time, I had no interest in incorporating Bari's Rim Route data into travellermap.com. Although neither data set was strictly canonical, I was interested in the Core Route because it was well researched and represented a canonical concept.
...
Since then (2016 or so?) I have reached out to Clifford and been granted his permission to incorporate Bari's Rim Route data, and have a copy of the sector data and notes (in GAL format, for those keeping track). However, it's a substantial data set (
around 200 sectors). There's cleanup required, border generation required, and I'm worried about the performance impact on the site since it's just plain
huge. This hasn't been a high priority for me, but it's on the "to do" list.
Also, and I'll be blunt: I don't feel that Bari's Rim Route data is compatible with the OTU. Along the route are many, many large polities comparable in size and technology with the Imperium. The final sector is an amalgam of science fiction fan references. It's a lot of fun, and I think the data should be preserved as an important contribution to Traveller lore, but... I think it needs to be treated specially.
My plan is to allow access to the route via some option, but it would not be presented by default. The site currently includes experimental "milieu" support (e.g. M990, M1120, M1248, etc), so that's a possibility.
Note that some of the currently presented sectors are designed by Bari as part of his route: Phlask, Drakken, Lorspane, Darret, Ataurre, Muarne, and Lancask. I may remove some of them from the default data set.

(To just to be clear: the inclusion or exclusion of data on the site is entirely at my whim -- subject to any limits imposed by the Traveller IP owner, i.e. Marc Miller, and the individual authors. So if you would like to see something included -- or excluded -- talk to me. But there's the possibility we'll disagree. I may also change my whims at any time.)
Well, I see Mintaka and Joyce's Void, but I don't see the rimward expedition.
Those are by COTI member 77topaz who's been charting a cluster of sectors as part of the "Orion Association" setting. Technically non-OTU/Faraway/etc. Since they're not overlapping Charted Space and associated with specific rifts nearby I'm keeping them in place.
And I see the Zhodani coreward expedition, but I don't recall anything ever published for it.
Hopefully covered above. The site is offline now. If you explore the documentation on the site you may be able to find links to the Internet Archive's partial backup of Clifford's site.
And I thought K'Keree space was mapped via GT, but the central sectors are empty. So, I'm just a little confused on what gets included and what doesn't.
The K'kree sectors were never detailed, in GT or otherwise. The GT Aliens modules dropped some details about some adjacent polities and all of the various stabs at alien modules have given some details about worlds here and there, but no-one has published any sectors in K'kree space. COTI's GypsyComet has been working on charting them out recently - some placeholders, but working from the outside in so the central sectors are still blank.
Again, the gruesome detail for everything is captured at:
