I wouldn't expect them to. Almost(?) nothing in Guix links to the
'glibc' in (gnu packages base), so I wouldn't expect them to link to its
replacement either.
Most packages are linked with 'glibc-final' in (gnu packages
commencement), and we should expect them to now be linked with *its*
replacement. Try this to find the expected glibc-final replacement:
./pre-inst-env guix build -e '((@@ (guix packages) package-replacement) (@@
(gnu packages commencement) glibc-final))'

Thanks for the heads-up, and more generally to your prolific
contributions to security in Guix!
