$RedirectDelay is there because some rare sites wish to display a
short notice when a redirection occurs.  I don't know anyone who actually
does this, however.

$EnableRedirect is almost strictly for debugging/diagnostic purposes.
Again, I don't know anyone who disables it (and anyone who does is
going to find things such as ?action=edit very annoying).  

Both of these variables are only indirectly related to the (:redirect:)
markup, their primary purpose is diagnostic.

Yes, that's why it's there.

For this it's probably worthwhile to use something other than Redirect().
Either that or it may be useful to get Redirect() to always use 303 --
I'd have to look into it.

Makes sense, I'll add that soon.  But since the vast majority of sites
keep $RedirectDelay=0, there's little need for seeing this.
