The answer is that when you want to add something new to the <head>  
element, it makes sense to consider using <meta> and <link>, and that  
adding attributes to them is not a big deal, because it rarely happens  
that we do so. In the close to eight years the WHATWG has been working on  
HTML, we have added one new attribute, to <link>.

Your argument is similar to why some people think HTML should have  
namespaces. And it does not make much sense. I mean, we could have a  
million elements in theory and we might need to disambiguate them if we  
do, but in practice HTML aims to address the common use cases and can  
therefore do with a relatively concise vocabulary. That also allows it to  
be widely implemented by many user agents in the same way.

There will be a relatively large change (larger, as it more complex) if we  
add a new element too.

You do not create a conflict by adding new attributes. That makes no sense.
