I can't think of any other uses, so yes. Lennart may want to comment.

I may be misunderstanding, but I think you're sort of implying that IDNA
(in domain names and URLs) is the main use for confusables.txt. I think
file names, shell interactions, and general text (especially source
code) are also important uses of that data because confusables in those
settings can introduce security issues. Sorry if this is clear to you
and everyone else.
