I think it's a bit of both.  I skimmed through the past discussions and
found that not only was there a rough consensus in 2024 that stats _should_
be on by default [0], but also that an updated vote tally didn't show much
of a consensus at all [1].  Like you, I thought we had pretty much closed
that door, but the aforementioned analysis along with further discussion
has me convinced that we might want to reconsider [2].
