Yes, and it’s even unavoidable for software that depends on (guix …)
modules.

It’s not too bad, but (1) it could break the user’s setup (for instance
if they’ve installed some incompatible Guile versions via the host
distro and all of a sudden Guile 3.0.9 modules show up in the search
path), and (2) one could just as well consider special-casing ‘CPATH’ or
‘GUIX_PYTHONPATH’.

So I think we can close, but again, if I misunderstood how the status
quo is a hindrance, I’m open to this change or any other solution.
