Hmm... that argument suggests that typical web browsers are not HTTP 
since they do so much more. It doesn't appeal to me. The rest of the
argument is more persuasive...

OK, that makes sense... it's a little bit like whether to load images 
or not,
if it weren't the norm to load them pretty much every time.

It's possible to squint and look at that as a matter of "local policy
and configuration". That's a stretch... perhaps "At user option" 

Try this on for size?

A GRDDL-aware agent is a software module that computes GRDDL results of 
information resources. Given a URI I of an information resource IR, and 
an XPath node N for a representation of IR, a GRDDL Agent should, at 
user option and subject to security considerations below:

    1. Find each transformation ...

Yes, but we have new information since that decision, so the
chair re-opened the issue 14 Feb, whence comes my action and
this thread.
