If the POSIX committee couldn't deliver a solution that was modern and backwards compatible, what hope do we have that developers will selforganize and ever do that?
Q1. What is the Portable Application Standards Committee (PASC)?
The IEEE Computer Society's Portable Application Standards Committee (PASC) is the group that has and continues to develop the POSIX family of standards. Historically, the major work has been undertaken within Project 1003 (POSIX) with the best known standard being IEEE Std 1003.1 (also known as POSIX 1003.1, colloquially termed "dot 1"). The goal of the PASC standards has been to promote application portability at the source code level.
