Comment:

 Well, I can answer those!

 template_redirect is a hook, not a filter, so it doesn't give you access
 to the template path that's been chosen or give you a chance to change it.
 It's called before wordpress even decides what template to load.

 There are *_template filters, but it's not possible to enumerate a
 complete set of them and hook them all: the attachment filter, for
 example, generates the filter tag by looking at the MIME type of the
 attachment. Since plugins can add whatever mime types they like, it's not
 possible to generate a complete set of *_template filters to hook into.

 The Carrington template appears to use the is_* functions to figure out
 what template it's in -- which is fine. We're not trying to do that. We're
 trying to change the default template loader's behaviour, so executing
 code after the template has already been chosen and included won't work.

 What's the harm in adding this as a new filter?
