Sometimes it's just curiosity ;)

For example:

Although this is just one case.

If you're trying to display anything related to the /visual/ appearance,
you'll have to consider the possibility of overlays and thus run into
the same issue.

If I'm not mistaken, there were a couple of other packages that handle
this (highlight-indentation?) if you use pretty-symbols or similar
modes, and the way you have to do that is not pretty.

Looks orthogonal to me.
I don't have a need for it right now, but somehow seems logical to have.
