Emacs users know the Emacs regexp syntax.  They may also be aware of
other variants.  There's nothing "special" about Emacs regexps - their
makeup is simply one variant amongst several.

I very much doubt users will be "very happy" about having to choose
between two regexp syntaxes.  I expect they are "happy" that each
program they use has just one regexp syntax, if they even think about
that at all.

Introducing an alternative regexp syntax would cause bloat (which Emacs
isn't short of), and impose extra work on Emacs hackers everywhere, who
at the very least would need to put something like

   (let (alternative-regexp-syntax) ....)

around all their entry points.  I don't want that extra hassle, that
extra bug source.

In short, this proposal is a proposal to increase complexity, increase
the workload on all hackers, and a source of future bugs.  What we've
got already works well enough.  Why change it?
