Yes, you are on the right path here. Regarding your questions:
1. I'm not sure, maybe @joel knows. It's possible no one ever asked for it. I suspect it would be useful to have it. The API is documented at https://docs.rtems.org/docs/main/c-user/message/index.html in case you haven't read it yet.
2. If I had to guess, I would say that POSIX uses `_Submit` directly because it uses a priority value, whereas the `_Send` appends to the end of the mq, i.e., treats it as a FIFO.

Related to point 2, the Classic MQ does not support priority-based insertions. That might also be a worthwhile extension of the classic API.
