I disagree.

1) Conflicts *do* occur, as soon as you consider extensions that happen 
outside the microformats process (and that process seems to exclude 
private extensions, such as for intranet applications).

2) As a matter of fact, <http://microformats.org/wiki/profile-uris> states

"In hcalendar-issues, it is ACCEPTED that each microformat should have a 
profile URI, like the XFN profile (http://gmpg.org/xfn/11)."

So it seems you are in disagreement with the microformats community as well.

That being said; I agree that the profile attribute is not a good 
solution, as it is of limited use only. Thus, instead of removing it we 
should think about fixing it, or using something that works instead 
(RDFa comes to mind).
