Testing "guix pull" to detect earlier breakage is a recurring topic. :-)
Well, "make as-derivation" or almost equivalently"./pre-inst-env guix
pull -p /tmp/new" are the tools to do so.  But they require some CPU
time, so they are not always done before pushing.  And when it is
pushed, it is too late.

Even if the CI detects the failure, this will not prevent the end-user
for pulling something broken.  It is because the model: push directly to
master without any CI validation. Something is wrong with this model
when we speak about annoyance by little errors.

The end-user should (only) pull (by default) commits which pass the test
suite *and* where the substitutes are available.
