Ah, that's a clever trick. The clone protections try to prevent overriding
the `core.hooksPath` with a valid (but not intended by the user) path.
What you are doing is to specifically turn hooks off *1*.

I plan on sending out a patch series later either today or tomorrow to
address a couple of regressions introduced by v2.45.1, and this patch
would address your specific scenario:

That is certainly a good work-around for now. Thank you for the report! I
hope that we can address your use case in v2.45.2, hopefully soon.

Thanks,
