Hm. I was not aware of the Heirloom project. I'm glad someone
is doing this, and will add a link to it from my Retrocomputing
Museum page.

Sorry, I have to ask this because you're not a native English speaker
and the above seems technically implausible: did you get the sense of
the negative in that sentence reversed? That is, if
A = .br .nl .sp .bp .ft .fi .nf .ul .cu .tm .so .ds .as .rm
.rn .em .am .nr .rr .ig .pm .cc .c2 .ab .do
are you saying:
1) Heirloom troff supports $A plus .fam
or
2) Heirloom troff supports $A plus .nop .return .mso .als .shift
?

I didn't think so. manServer was one of the sucks-pretty-badly
translators that made me dissatisfied enough to write doclifter.
The others were man2html and a project that (I think) used to
be called CMan and later changed its name to RosettaMan. To be
fair, though, manServer is probably the least bad of the three.
All three have the same flaw: too close to presentation level, almost
no attempt to recognize content patterns. I knew I could do better
than that. (My background in AI popping up.)

Agreed. Based on your experience of multiple *roff implementations, what
would you propose as a safe set? You are probably the only person here
with experience of even more weird *roff variants than I know about,
so I would put your judgment on this above mine,
