The point is that whether to turn this on by default and for which
platforms was never discussed.  Dmitry asked for help in testing that
on Windows, and I provided my conclusions about that.  Another user
reported problems with clang.  That's it; no further discussions were
conducted.  What you say above does not (and cannot) refute this basic
fact.

This is not how this should be done.  We should discuss first, arrive
at some conclusion, and only then act.  This is a team project, and no
single one of us can hope to grasp all the effects and consequences of
any serious changes such as this one.

On the contrary, they were well deserved.

So do I, but that's another issue, unrelated to what I protested
about.
