I have the idea to support other templating languages by allowing files 
with other extensions in there, eventually.

Do I understand it correctly that the goal here is to control the output 
mime type? I wonder whether we don't simply want to support a 
grok.mime_type directive on views (and your solution for the inline page 
templates). Such a separate directive allows view subclassing and such, 
which your grok.template doesn't support, I think.
