I don't know if it is still used by the maintainers for preparing a
release.  I do know that there are no version numbers in the source
files any more, so that part of set-version.pl surely is obsolete.  The
other parts may become obsolete if whatever is still in used can be
moved to make.  I've already started to reduce the reliance on perl in
my branch, switching to sed where possible.

Again I don't know if or when this gets merged.  I've already used up my
TINYCHANGEs and hit an impasse with the FSF papers that I don't know how
to resolve... :-(  Then again, the build system doesn't really become
part of Emacs, but it's up to the maintainers to decide.

I'd much prefer to inject the version in a different way, not making an
altered copy that the build works from.  The result is the same, but it
doesn't feel OK... so probably the solution should be to get the version
injected via some @set in an @include file (that's the recommended way
from the Texinfo perspective, anyway) that is produced by make whenever
the source file changes.

I posit that if it's worth to have that (I'd say yes), ``make info´´
should do that, in a way that is compatible with version control.
Anyway, I've implemented the requested functionality into my Makefile
fork, please test.
