So far so good ..., unfortunately none of the actual browsers supports it, even
though sites like 'Can I use' ( report calc() as
Indeed it should say that it is only 'Partially supported'.

Sorry, but here I have to disagree! In RWD it is essential to use em unit and
therefor it would also be quite important to ensure that an author may stack his
MQ rules, no matter what the user has set his basic font size to.
This could only be achieved by using the calc() syntax.

And beside of the question if it is useful or not - if the spec allows for it,
it should be supported!
So it is not a topic for this list, but rather one for the browser vendors.
