What about a Sony Ericcson phone which unknown product ID? We have two
templates for vendor=Sony Ericsson.

I agree that if the vendor matches exactly one template, preferring that
template makes sense. I can imagine corner cases where it is not the
right one (unknown Sony Ericsson phone which behaves like a Nokia), but
that should be unlikely. So we should take advantage of the more
reliable information to propose only one template.
