A mount option assumes that you can do with or without it. If you do it
once, you can mount the next time without it and stuff Just Works. Even
htree follows this. A clean unmount leaves a clean directory structure
that a non-htree driver can use.

I suggested this somewhere back in the thread and it got no play. What's the problem with doing things this way? (Aside from it being a compromise that doesn't automatically result in a new ext4)

Of course, there are a few debates going on here. Only one of them is about compatibility.
