Um, no, you are incorrect.

Only UNIX(TM) systems are allowed to ship nroff and troff.

All other UNIX systems (including the BSD systems and non-UNIX systems) 
have to ship an alternative.

groff is what most of them use, and it was designed to replace troff, 
and emulate nroff and get as close as possible to the "real thing".

groff is a totally new program, with different internal data structures, 
and quite a few improvements over troff.

That means a lot of macros had to be rewritten.  There are also legal 
issues that affect compatibility.

The goal of the groff macros are to get as close as possible to the 
output generated if you were using the "real" UNIX typesetters.

All things considered, I would say that groff does a very good job of 
providing an nroff/troff alternative to non UNIX(TM) systems.
