This was incredibly helpful to understand how the cache functions work,
since they use catchall a lot.

Not sure I understand the question. Why would it be safer or less safe
to move the "remote" directory somewhere else?

Note that we do the same for http i.e. start a webserver on the local
machine and then access (local) repos via http. I guess nowadays this is
what everyone does. I find it less obvious that we also have tests that
connect to actual remote machines on the internet ;-)
