[racket] pregexp vs regexp

As far as I can tell, pregexp functionality is a superset of regexp
functionality.  Furthermore, the added functionality uses patterns
that are unlikely to occur by accident in normal regular expressions.
So is there any advantage to using regexp over pregexp?  Why is there
a need for both to coexist in Racket?  What would be the downside to
removing regexps from the language?
