Well it may imperfect but its certainly predictable, once you've used it a few

I think you exaggerate the frustration it will cause. The user can quickly
find its limits.

That heuristic is aready used in startup.el so it must be pretty good. If
there are cases that aren't covered, hopefully they'll come up in the pretest.

I say let's enable it by default, I think Richard has already decided this.
Single mouse clicks work on the modeline and eleswhere now. I certainly think
most users would use it by preference.
