I skimmed it briefly, and I don't see an architectural conflict. I'm not
convinced it's worth adding that information, but that's a separate
discussion.

Neither should have been added imo. We're already at 9 different reset
functions. Without a unified function to reset all stats, pretty much the only
actually relevant operation. And having pg_stat_reset_shared() with variable
'reset' systems but then also pg_stat_reset_slru() and
pg_stat_reset_subscription_stats() is absurd.
This is just making something incomprehensible evermore incomprehensible.

Not in isolation.
