Thank you. I cannot tell which list that discussion was on, but I see
that the change was made unilaterally, complaints were raised (including
about the lack of prior discussion), and most of the arguments FOR the
change were from 3 people. Most of the arguments AGAINST were from well
known operational and security folks, and the authors of SSH.
Yet the change stayed.... undocumented, more than a year later.

I vote for whatever behavior compatible with stock OpenSSH, by default.
I don't think it wise to surprise people.

... A few sentences
explaining why the flag is off by default as comments just before
the flag itself is possibly helpful to new users. Comment text
of any variety surely is not much inconvenience to someone who
wants to defeat the config defaults when settingup a new machine.

... People compensate for that with a
variety of hacks (often involving sudo) that tend to promote the
illusion of more security, but not the reality. And the reason for
that is that "privileged", non-root access to a machine is often
equivalent to root, but via a few extra, trivial steps.
