That particular example looks awkward, but pls don't forget that
users (mostly) have been happy without any option of quoting so
far.  IOW, there shouldn't be much to quote in real life.  I can
provide a simpler example in the manual, but that's probably not
what you meant :-)

Agreed.  It introduces more context, and longer context, than a
simple backslash.  Plus double quotes are already used for other
purposes in the larger regexp, which could introduce more
ambiguities.

Finally, a term

  "foo-bar"="foo-bar"

looks, er, tautologically? at best.
