I'd be willing to compromise on just adding TS_EXEC_CALC_NOT to the
calls that are missing it today. But I don't see why that's really
a great idea --- it still leaves a risk-of-omission hazard for future
callers. Calculating NOTs correctly really ought to be the default
behavior.
What do you think of replacing TS_EXEC_CALC_NOT with a different
flag having the opposite sense, maybe called TS_EXEC_SKIP_NOT?
If anyone really does need that behavior, they could still get it,
but they'd have to be explicit.

The other issue we have to agree on is whether we want to sneak this
fix into v13, or wait another year for it. I feel like it's pretty
late to be making potentially API-breaking changes, but on the other
hand this is undoubtedly a bug fix.
