It's not that I don't want that.  I actually am quite indifferent to
this, because I think dir-locals, in its current design, is too
restrictive, and therefore I'm simply not interested.

I just think that adding these implied conditions is a slippery slope,
because different people want to do different things with dir-locals.

That looks better, since it at least makes the user's desire
explicit.  Why not implement it?
