The regexp specification is not an Emacs-only feature, and I don't
think we should invent a variant of regexp spec where these particular
regexps are disallowed.  It sounds like a step in the wrong direction,
since there are already too many variants of regular expressions.  And
the particular reason for which you propose this change sounds
backwards to me.

So thanks for volunteering, but I don't think we should do this.
