This looks like Savannah #63924.

Does Illumos continue to use the AT&T troff descendant that Solaris
shipped with version 10 but (as I understand it) dropped in favor of
groff in Solaris 11?

If the latter, there is likely little or no reason to have groff install
compatibility wrappers around an older version of groff.
