Why fix what isn't broken?
1) Some people think it IS broken.
2) Even if it isn't broken, the 'fix' improves the verisimilitude of the setting considerable.
Take Regina's TL - all the early adventures that feature Regina have TL A, the FFW has TL A, even Scouts has TL A. Why does a typo in SMC (of which there are many) become redacted canon?
Several reasons.
a) The very earliest canon (
The Kinunir) shows that Regina is capable of building jump-4 ships. Which was fine back when we thought that TL 10 was enough to build jump-4 drives (the way Book 2 claimed). But later we found out that Book 2 was in error. HG told us that you need TL 13 to build jump-4 drives. So if Regina has a High Common TL of 10, its Space TL is three higher than its High Common, which is very unlikely. But if Regina has a TL of 12, its Space TL is only one higher than its High Common, which is pretty unexceptional.
b) Regina has been the most important world in its neighborhood for over a millenium. It's a rich world and a trade center and has a popultion in the high hundreds of millions. It's actually pretty odd that it isn't TL 14 or 15. That it's only TL 12 is odd enough, but at least it's better than Regina being TL 10.
c) Regina has been TL 12 ince SMC. Why change it back if it work?
So there is one jump 5 x-boat route - explain it don't bin it.
Now why didn't I think of that?
Oh, wait... I did. I tried to explain, but wasn't able to come up with anything that didn't snap my belief suspenders. As a matter of fact, I've tried to explain every bit of canon that I advocate changing.
But I'm always happy when someone comes up with a plausible explanation
that doesn't create greater problems elsewhere. The last bit is rather important and is often ignored when people try to explain away odd UWPs. Take the jump-5 route for example. The problem isn't so much to come up with an explanation why Strouden and Extolay rates a jump-5 connection (though that's a bit of a poser in itself, at least if Extolay really only has a population rating of 1) . The trouble is coming up with an explanation that ALSO explains why no other 5-parsec route in the mapped part of the Imperium rates a connection.
Use imagination rather than just producing a redacted bland SM.
This statement makes the assumption that fixing inexplicable UWPs doesn't require imagination and would produce a redacted bland Spinward Marches. I think such an assumption is completely unwarranted.
