I concur.  It's a great feature to have during debugging but I
wouldn't want to slow down a production instance with this feature.
Debugging tools like DUMP don't belong in production.  Having the DUMP
directive be available for use in a development environment but not in
production sounds OK, but not at the cost of slowing down production.
