Oh got it.  So yes, your proposal makes a lot of sense to me, Lars.

The way to do that is to add (guix build python-build-system) to
#:imported-modules and #:modules in those packages, and then to use
‘modify-phases’ to add that ‘ensure-no-mtimes-pre-1980’ phase to those
of ‘gnu-build-system’.

How does that sound, Brian?

We have similar shenanigans for other packages that use a primary build
system but need stuff from another one.

Thanks,
Ludo’.
