Would not forcing regexes into two different groups change the regex
evaluation order and, hence, make it more difficult for some admins to
optimize their regexes by placing frequently matching regexes earlier?

I am still not quite sure what problem we are trying to solve exactly
here, but allowing admins to control exact regex evaluation order seems
important [for some admins].
