There are other places in the tree it's set to true as well. Are they needed for some reason?

I think it is needed in some places possibly due to some overflow or underflow being intended in some places in the runtime? It's just a guess on why it might be true in those spots or if it's set to true just "in case" something like that happens.

Either way I think it would need some extensive tests to make sure those are not needed first.

I see exactly one under runtime tests. It can be trivially replaced by enclosing the body of the test in checked context if we do not want to have CheckForOverflowUnderflow in the test csproj.

Yeah, not sure where I was searching before when I saw pages of results (both false and true), but we might as well just get rid of it entirely.

Seems to be a unrelated test (rebasing on main might help)

Please let me if I also need to remove CheckForOverflowUnderflow from

Yes, please remove it and add checked block to the test source instead.
