But ideally we'd just make it safe to dump and reload stats on your own tables, and then not worry about it.
That is my strong preference, yes.

To me it seems like inconsistent data to have most_common_freqs in anything but descending order, and we should prevent it.
Sorry, I misunderstood, I thought we were talking about values, not the frequencies. Yes, the frequencies should only be monotonically non-increasing (i.e. it can go down or flatline from N->N+1). I'll add a test case for that.
