I didn't mean to imply that's abnormal.

Maybe if the whole chainstate is rewritten, there's opportunity to check for complete consistency. Not that I know that it does that.

Anyway, I'm going to leave it be. The wallet state is as I expect it to be, and it seems to work. A pre-crash wallet backup should suffice. Worst case I'd have to do a fresh IBD from scratch, which would be a pain, but doable.

It would be more reassuring if, when restarting post-crash, Core would explicitly indicate that it's aware of the previous crash and that it checked or recovered successfully. I don't know, maybe it already does that in newer versions (considering I'm on 0.18).
