Do you mean he won't be able to copy it out of a newer CMake into his
project to use with an older CMake?  IMO that should not influence our
upstream decisions.  If you need this you can take the impl you have
in the topic now and use it elsewhere.

CMake's own modules can be updated to not include the legacy module.
Project code will include it and it will do nothing.  I do not see
a problem.
