As part of the protections added in Git v2.45.1 and friends, repository-local `core.hooksPath` settings are no longer allowed, as a defense-in-depth mechanism to prevent future Git vulnerabilities to raise to critical level if those vulnerabilities inadvertently allow the repository-local config to be written.
What the added protection did not anticipate is that such a repository-local `core.hooksPath` can not only be used to point to maliciously-placed scripts in the current worktree, but also to _prevent_ hooks from being called altogether.
We just reverted the `core.hooksPath` protections, based on the Git maintainer's recommendation in https://lore.kernel.org/git/xmqq4jaxvm8z.fsf@gitster.g/ to address this concern as well as related ones. Let's make sure that we won't regress while trying to protect the clone operation further.
