Review Comment:
Extra round trips
(https://github.com/apache/superset/pull/41754#discussion_r3529843835) — yes,
conscious call, with these bounds: a saved aggregate + summary chart does zero
extra work (totals ride the initial formData-driven query; the nudge only fires
in the renderTrigger gap). A saved raw + summary chart pays one priming
re-query on first load — the base query is a server-side cache hit, only the
totals query is new work. The toggle-off reset query is the deliberate
trade-off: the alternative (clearing the flag when data arrives) would fire an
extra query after every totals fetch, which is strictly worse; toggle-off stays
visually instant regardless because the grid gate hides the row before the
query returns.
