That doesn't follow.

You are right to bring up this issue. Many people do think current
"smart" mode is annoying, though we must accept that some people like
it *and* that changing the default behaviour in one release is a bad
thing.

I don't think anyone has spoken against introducing a new mode. Having
it is a good thing, whether or not it is default.

So lets implement the new shutdown mode and work out a transition path
to a new default. Changing rapidly screws up the people we love the
most.
