No objection to this, but FWIW the general pattern for these object.h
flags is to use these un-prefixed names:
git grep -A20 'Remember to update object flag allocation' | grep define
To be fair the only one that's really comparable is the revision.h ones,
but those are very non-namespace-y, with names like SEEN, ADDED, SHOWN
etc.
I'd be fine with just leaving these as-is, especially with compilers
warning about macro re-definitions.
