That sounds quite reasonable.  It's much more important to program
defensively when doing CGI programming; using dispatch tables makes error
handling a breeze:

	if ($dispatch{$cgi_param}) {
		## do something
	} else {
		## standard error handling
	}

or even 

	throw_error_and_quit() unless $dispatch{$cgi_param};

	## no worries here

And, of course, maintenance becomes *much* easier.

Sorry if this was an obvious insight or otherwise mentioned.  I haven't
read the drafts yet.
