What mechanism did you use for base URLs? Or is the cost there deemed
acceptable?

For direction you need to have a similar mechanism available. (And
you'll have the same problem roc pointed out with :lang() if you solve
that through CSS as :dir(ltr) and :dir(rtl) exist these days.)

If browsers already implement some kind of API for these things it
might be worth to expose them in the same way.
