My objection is that "reset_table" sounds like something you do to a
table, not something you do to stats.  No, I don't think the prefix is
enough to clarify that.

In that case, there's nothing but the "stat" to suggest what gets
reset, so I think it's less likely to be misleading than the current
proposals.  But if we'd been designing all of these at once, yeah,
I'd have argued for a more verbose name for that one too.
