It's definitely a bug, and I'd like to see it fixed, (along with many
similar bugs where the X limits on drawable coordinates leak all over
into limits within cairo's implementation).
In this specific case it looks like we simply need to fix
_cairo_surface_clone_similar (and all backend->create_similar
functions) to accept a rectangle of interest (x,y,width,height) as is
already available in _cairo_pattern_acquire_surface_for_surface.
But Alexander and Federico still have quite valid points questioning
what you are doing. You yourself said:

Infinite zoom is very useful. But it will make your current
caching scheme entirely useless, right?
