I'd rather see them and have the use of a quick Ctrl-K# rather than trying to nest a lot of identifiers. I can just imagine what someone trying to make rainbow text would need to do and how confusing it would look (not that I like rainbow text, but it was an example). Obviously, you can script a loop to do it without the identifiers, but if you do, then you're still doing it the same way as it is already.
