Bug 24563 appears to still be open and unresolved.  What do we have to do to close this bug and my associated ACTION-65?

See https://www.w3.org/Bugs/Public/show_bug.cgi?id=24563#c35


I think I will keep the action open until the discussion on this bug dies down.

There's
https://www.w3.org/Bugs/Public/show_bug.cgi?id=24563

and that just got resolved with Aaron's new proposal, which also makes a lot of sense to me.

I think you can close this ACTION.

Cheers,
Silvia.
