For example the W8
was a flat fare replacement for the 128.
So presumably for most of the routes it is just
a historical thing and as there has been no need
to change the route numbers they have been left well alone.

Although it is slightly odd that they have been left alone, because routes
with a letter suffix (as opposed to prefix) have been systematically
renumbered. Perhaps the suffix ones were mostly 4 characters long... Maybe
the suffix routes with 3-characters have remained unaltered.

Incidentally, I think that the W10, P13 and several of the U routes in
Uxbridge have had the same fare structure as every other bus in London since
introduction.
