Now that's interesting: Suppose we have file foobar.el(c) from Emacs 28
installed by "make install" somewhere below, say, /usr/local/...

Suppose further foobar.el got removed in Emacs 29.  Will it be actively
removed from /usr/local/... by a "make install" of Emacs 29?

Not sure whether this is what is worrying the OP, but that (and, more 
generally, version consistency issues) would worry me if used "make
install" to "upgrade" a local installation.

Or have I missed something here?
