That argument could be used for adding millions of features that would see 
just as much use as profile="".

The point is that profile="" has had over a decade to prove itself.

The reasons for removing profile="" are that it isn't used much and has 
few use cases for which it is of any use. Indeed, outside GRDDL (whose use 
of profile="" is somewhat dubious as discussed in earlier e-mails, for 
example it has apparently resulted in two URLs being used for hCard) I am 
not aware of any use case at all, and I'm not convinced that the GRDDL use 
case makes sense when taking into account typical authoring practices.

With all due respect, there isn't that strong community support for it. 
There is one relatively small community asking for it, the GRDDL 
community, and even within that community not everyone seems to agree that 
it is a good idea.

We don't add or keep features because they cause no harm, we add or keep 
them because they do _good_.

But in any case, I've already said what the harm of profile="" is. It 
encourages inventors to think that declaring vocabularies is a good idea.
