GRDDL isn't going to work very well using the profile="" attribute if it 
requires something that profiles don't do.

There's no exclusion, we have a generic extension mechanism for linking to 
things (<link rel>).

The market has already chosen -- the vast majority of pages that use 
Microformats or other mechanisms that are supposed to have profile="" 
values (e.g. hCard, Dublin Core metadata, etc) don't have them. That's why 
we're dropping it from HTML5. There's no point including a feature that in 
practice is ignored.

To be honest I don't really understand the reluctance from the GRDDL 
community here. profile="" doesn't work, people don't use it. Surely the 
right thing to do is to take that into account and fix GRDDL to work with 
real world content. Why would you want to cling to something that has 
widely been ignored and will make it harder to use GRDDL on the Web?
