I don't think that bashing on people will bring your issue forward.

Yes, certainly. An implementation of the C1x stuff has to provide the
right arguments to the OS implementation of threads, e.g if the the
underlying implementation is pthread, it has to set the attribute
argument properly, if the default for pthread is not conforming to
C1x. I don't see a particular difficulty in that one, it is the C1x
thrd implementation that has to provide these arguments.

You would be right in saying that this model is kind of restrictive,
allowing for only one execution model. In particular it is a pity that
it doesn't allow to start threads in a detached state.

Hm, since it doesn't define the term "suspended state" and supension
of a thread is only done via a sleep function for a limited time, I
don't really understand your issue here.

Here, a better wording would probably be appropriate. I think
injecting the word "specific" before "resources" would already be a
good disambiguation.
