But while people were waiting for browsers, they added duplicate <a>  
links to their pages. Why couldn't those have been the same thing?

I don't see how that follows. Non-browser user agents can look for <a  
rel="feed"> in the content just as readily as <link rel="alternate">.  
There is no need for the browser's permission to include either.

And with <a>, content authors would not have to wait for *any* tools  
to provide additional support, even non-browser tools, since users  
would be able to see and click on the feed link.

I don't think this is relevant to the claim at hand. We're talking  
about two different existing extensible mechanisms that are already  
understood by browsers. The difference is that one of them had a  
visible end-user effect without the need for new browser features.

Thus, visible metadata reduces the need for browser involvement in  
web innovation.
