AFAICT they're already escaped (with \=), so that would not be worse, or
am I missing something?

That's a downside, but \ is "the standard quoting method", so I think
overall it could be counted as removing an escaping method rather than
adding one.

Hmm... yes, the idea is to use \ instead of \=, everywhere.

We'd probably want to keep supporting \= for a while anyway.

Which case are you thinking of?
