Something like that is certainly fine.  I guess I'd phrase it like this:

This appreciation persists even when some particular work is no longer part
of @theglibc{}.  Some of the contributions listed here have been removed
entirely in the years since the work was done.  While the code will always
continue to change and no part of it lasts forever, the gratitude toward
all contributors, past and present, is eternal.


Thanks,
Roland
