Bug #40717 covers modernizing groff's font support, a massive undertaking.
But even with only PostScript Type 1 support, as groff presently has,
incremental improvements can be made.
One relatively simple one is to expand what ligatures groff recognizes. The
current hard-coded five (fi, fl, ff, ffi, and ffl) are based on the C/A/T, an
output device that hasn't been relevant in decades. Type 1 fonts can specify
arbitrary ligatures; a small but significant improvement would be letting
afmtodit generate font description files with these, and having groff use
them.
http://lists.gnu.org/r/groff/2013-11/msg00028.html has some design spitballing
that may or may not prove useful.
