Check out https://trac.torproject.org/projects/tor/ticket/15622
for more discussion of this idea.

I think the main problem with it is that we'd have to pick, and stick
to, a particular format. The "let people add hyphens wherever they think
it improves usability for them" option has all sorts of unexpected side
effects when client-side apps accidentally reveal the hyphenation choice.
