If I see any free operating system distribution released within the
next five years which fails to support the old syntax, I will file
maximum-severity bug reports.

I went through it more carefully; the only problems that jump out at
me are sort -u and diff -C. You may have better information about
when these came into vogue, but I'm pretty confident that systems the
didn't support either were still in use in early 2001 (last time I had
access to a wide variety of Unix variants).
I'm disturbed to see uniq dropped from POSIX, there are things that it
can do that sort can't, as far as I know. (-d, -c)
