In #1888 we turned off decide := true as the default behaviour in dsimp.

I think at the time my intent had been to turn this off in simp as well, but that's not what the PR did.

Since then issue #2068 (see also related zulip thread) requested that we turn it off in simp as well.

I will compile mathlib against this PR in case of regressions there.

Definitely not working out of the box. :-) I'll try again later.

You're not the first one to notice that this requires more than changing the default. 😄 #2068

FWIW I think false is the right default.
