I'm aware of that and didn't suggest otherwise.

I was replying specifically to:

we could build consensus to perform a deprecation of the existing method.

This suggests that the order is:

1. put it in base
2. wait 3 releases
3. build consensus about deprecation

I pointed out (and you did now, too, more elaborately) that in the case
of MonadFail, the consensus about deprecation step (3) was done before
(1) and (2).
