> @lenary The only reason I didn't have a pre-commit initially is that many of the tests crash pre-patch. What's the standard thing to do in this case? For now, I'll have a pre-commit containing the ones that aren't crashing.

You did the right thing :) I didn't realise what proportion of the AArch64 tests were crashing.
