Yes, for sure. IMHO, the Guix way would be:
guix describe -f channels > channels.scm
guix pack --save-provenance
then later or elsewehere
guix time-machine -C channels.scm -- pack --save-provenance
It is a workaround of the bug your reported. ;-)
Does it work?

I think your tests about the patch are not correct. As I wrote, this is
what you should try, IIUC:
--8<---------------cut here---------------start------------->8---
Moreover, if you want to try the patch, you need to run:
./pre-inst-env guix pull -p /tmp/new
./tmp/new/bin/guix describe # return commit 12345
./tmp/new/bin/guix pack --save-provenance
./tmp/new/bin/guix time-machine --commit=12345 -- pack --save-provenance
and be careful with the '--localstatedir' and '--sysconfdir' variables
at './configure' time.
--8<---------------cut here---------------end--------------->8---
All the best,
simon
