The bulk of this code is not tied to that decision, but I think that it does implicitly turn it on for all working trees, and we don't want that.   If we cut that out (and possibly do it in a plugin), I'd be ok to merge this.

It seems I've missed something. Why you said *only* about WT???
How the rules for using filters will be provided?
Last time your patch was rejected because you placed .bzrrules
or something similar to the WT.

But anyway it should be done at branch level, not at WT level, is not?
Because there is branch.conf, but there is not checkout.conf. Yes?

What I'm missing there?
