Quite plausible, though I didn't try it.  In that case, though, 
'route delete' shouldn't take two arguments.  More precisely, if it's
going to use two arguments, it should validate the second if present.
That is, I have no objection to both

	route delete foo


	route delete foo bar

working, but the latter should succeed if and only if the route to foo
goes via bar.
