In this case not really--since "make check" tests guix the package manager.
You didn't change the package manager, so it wouldn't help.

The CI does that and then it also builds all the other packages, not just
guix the package manager.

./pre-inst-env guix package -i emacs-exwm

The package is then installed into your profile and you can just use it like
any other packages installed in your profile.

That would work as well--but sounds like a lot of work.  It is nicer to
do it your way if you want to *keep* your package across updates if
it doesn't make it into the main repository.  Otherwise I don't think
your way gives you any advantage over just installing the package.
