From my perspective display would be akin to str()/#to_s in Python/Ruby.
So I was not thinking to tackle pretty-printing in general.

My *very personal* main use case, that I don't see other good solutions
for, is string interpolation.  Currently I have a crude hack in
interpolate [1] that does the right thing for String, Text and many
prelude types (see also [2] if you are curious).

But even more important to me is that we come up with something that is
general, has minimal dependencies and is not controversial, so that
people are willing to depend on it and provide instances.
