It's not completely clear to me when this feature is used in practice.  It would be nice to remove it or change the default behaviour if possible, rather than require a new option, but I'm open to this approach if we think we can't change the default.

Given that there was a recent change <https://reviews.llvm.org/D124946> related to `ORIGINAL_PCH_DIR`, I'm reluctant to change the default at this point, I added a `FIXME` for following up to see if we can remove it or change the default later on.
