I meanwhile remembered that the policy in LLVM is to squash-and-merge, so I guess you can supply a more useful message at that point, but I would still argue that the history deserves better than what is currently in this PR.

LLVM repo does not allow "merge" or "rebase", everything is squash, with ONLY commit message from the description. 
With or without spr they they are irrelevant.
