FWIW, I'd prefer we didn't proliferate prettify-symbols-mode more than
it is already, because I hope it will go away some time soon, to be
replaced by true ligature support.

Yes, it's pretty limited.  What's more, it uses infrastructure (static
character composition) that was a temporary hack way back, when
automatic composition was not yet available, and we should at some
point deprecate and remove it.

I suggest to only consider the second part of that ;-)

In general, you can hide stuff with display properties, and I'm unsure
what additional framework you'd need for that.

Thanks.
