RE: Do not remove the media attribute from the source element

Would one of you folks like to file the bug to re-add it to HTML5.1?

The desktop browsers, yes, and those mobile devices that I have been able to test on (slightly less than the list I gave earlier) yes.
I will write to caniuse.com<http://caniuse.com> as mentioned.
That use case mentioned in the bug report alone is a very good reason to keep the media attribute.

Are you saying that all these browsers support @media on <video> and
do the right thing?
If so, then it should indeed remain in the spec according to
cross-browser compatibility rules for features in the spec. After all:
the spec is there to describe what features are available in browsers.
At least it would need to be in HTML5.0. If all browsers decided to
remove it, it would then be deprecated for HTML5.1.

It would be worth talking to them about it.

Also, if you have more indication that this feature actually has a
good use case and that people will make use of it, it thus it doesn't
fail the "Real Problems" test [1], that would help make a better case.

I saw https://www.w3.org/Bugs/Public/show_bug.cgi?id=19619#c36 so
that's encouraging. Are there any other examples?
