A "fix" to the problem would be to introduce a commandswitch for enabling the
dangerous troff-commands, which is what I personally am going to do anyway..
looking at groff-1.10 and groff-1.11a,
I found -msafer option to DISABLE dangerous commands...
%%%% from "nroff -man $(GROFF)/tmac/msafer.n" %%%%
MSAFER(7) Device and Network Interfaces MSAFER(7)
msafer - groff -msafer macros
groff -msafer [ options... ] [ files... ]
The -msafer macros remove the open, opena, pso, sy and pi
requests. These macros should be used when processing input
from an untrustworthy source. For maximum safety, they
should be the first -m option on the command-line. Normally
they are invoked using the -S option of groff, which will
also pass gpic the -S flag.
