I'm pretty sure yours can't do all this in a single script, too. There 
will still be lots of input massaging and translation going on for each 
application.

Yes, sure, but then it's not that 90% of all recipes are doing input forms.

You're over-enthusiastic. You're not doing inline markup, mail 
protection, or a gazillion other things that recipes do. I'm pretty sure 
that the number of recipes that do input forms is below the 50% mark.

Don't include_once from a function unless you have tested the 
performance ramifications with a web server that has PHP caching. You 
might end up slowing down that particular configuration, doing a lot of 
work just to make the recipe worse.

I'd recommend something like this cookbook/data/data.php:
   <?php # PmWiki check goes here
   foreach ($_POST as $field => $value) {
   if ($field == "page")
     include_once (basename (__FILE__) . '/page.php');
   if ($field == "create")
     include_once (basename (__FILE__) . '/create.php');
   if ($field == "destroy")
     include_once (basename (__FILE__) . '/destroy.php');
   ...
   }
