1) Alright that works too thought I doubt there's any performance gain. I only use the experimental version anyway which basically does what you suggest just with functions.

2) Hmm, is that function called for every template? Might be a bad idea to clear the template cache 100 times when importing a style...not to mention importing a style doesn't require you to clear the template cache in the first place...? But for clearing the cache when editing a template might be worth a shot.
