Threats are not tolerated in this project. This hyperbolic response has
gone on long enough. Please stop and treat your fellow committers with
respect and a certain level of professionalism. He's done none of the
nefarious things you've said (I've known about this changes for days if not
weeks as he socialized it, for example). He doesn't deserve this level of
grief over a proposal. It's a request for comments, not a request for abuse
and nasty behaviour.

This whole thread has gone toxic / hyperbolic over a non-issue. You should
have stopped reading directories in 1983 when readdir was introduced
because UFS broke ls, find, du, etc. At best, it's a nice debugging tool
some folks don't want to lose. At worst, it causes bugs for programs that
accidentally read directories (and maybe some, like grep, need some minor
changes). It's not worth this much bile and venom.
