I agree.

Is that necessarily bad?  I'm not sure this will constitute a problem
in the usual cases.

I agree these modes are useful, but I'm not sure they should be the
default.  Yair wrote some time back that he intends to extend
whitespace.el to cover this functionality, so these ideas (all of the
good, I think) should be used there.

We could let the users use all those, plus the auto-composition with
the following character, and see what they like more.

In general, I believe the recommendation is not to display zero-width
characters.

Thanks.
