This is definitely the approach used by FSF/GNU - witness gcc and bash.

IMO, POSIX wouldn't exist without Unix.

That was my thought as well, though TripOS started in 1976 so it's likely
that the development team were aware of Unix and make have taken some of its
ideas onboard.

That said, Unix was not portable to start with.  I think that the important
parts were that the source was readily available within academia, it was
written in a high level language and it was small enough to be understood.
