I just ran across this new header while looking for something else. I want to discuss actually upgrading its 2 call sites by removing it.

This looks like a niche thing used in db/cst/ and put into util/, which is crowded.

It's a macro library, and what it does feels pretty specific to the needs of that project, and doesn't feel like it's going to be a good fit for util/.

Something similar was done in db/audit/action_types and it is really not so bad to rewrite it on the spot and get more flexible semantics.
