That's what I asked.  Do you know the answer?

We already guaranteed a proper build with older versions, since Guile
builds now with whatever minimal versions we were requiring.  So this
problem does not exist, and will not exist, unless we deliberately
start using a newer version.

That's not the point.  If a package requires a certain version, my
best bet is to use that version.

And some packages (e.g., GDB) indeed require use of a specific version
in order to make sure changes in the derived files are consistent.
