On my OpenBSD (6.3) boxes, there's no nroff/troff/groff nor any
ptx/gptx.

On my FreeBSD (11.2) boxes, I have nroff/troff/groff available but no
ptx/gptx available in base.  One of the machines has coreutils
installed which provides /usr/local/bin/gptx (and its man-pages).

So I can find it and read about it.  Just curious that it's fallen
out of base on both Free & OpenBSD (don't have a NetBSD machine at
hand to test that).
