Yah, so during my SoC time I will start with them first.
I guess I may find them on FreeBSD, had a little search on net.
Will get deeper in the topic once the sub-tasks are confirmed,
as for now I am going through tickets for POSIX Compliance.

Yah, i had this query in my mind, but then they were also not tagged as
POSIX_MULTI_PROCESS in FACE Technical Standards 3.0
and as you said about multi-process functions to be optional, i was not
able to conclude about them.
So I will leave it.
