Does it make sense to build RTEMS without the RTEMS thread model
enabled?
Yes. It makes sense to make it the default. I don't think this
matters much for C but it does for other languages including C++.
I could be wrong, but AFAIK, these days, threads are more or less
mandatory in C++.
IMO, it doesn't nor do I think it makes sense to build RTEMS with
--disable-posix.
For those writing C Classic API applications, there is no reason to
enable POSIX at this point.
That said, the community that does that may find themselves having to
enable POSIX if they move to SMP or C++.
However, in the past, there had been strong resistance to make threading
the default or mandatory. because of the overhead it causes in RTEMS.
Where?
Well, the origin of resistance sits in front of your desk ;)
