I always thought that was a very cool feature, mkdir+echo, poof done.
Now maybe that interface is suboptimal for serious usage, but it makes
the things usable via dirt simple scripts, very flexible, nice.

But whatever, not my call, you know your business better than I.  If
mandatory agent happens, fine, but imho that will be sad day.
