If they work without byte-compiling, they will also work the same when
byte-compiled, I think.

The Emacs source tree has more than 2300 Lisp files, and they can all
be compiled in under 5 minutes.  That's a far cry from "days".

In any case, feel free not to recompile your files when you upgrade
Emacs, and instead wait with fixing till things break.  But then
please don't come back complaining that something that was obsolete
for the past 15 years suddenly doesn't work, because we gave you 15
years to adapt, and you have chosen to ignore that.

Because it's an extra maintenance burden, and a serious one at that.
