It works for me, on Manjaro's (Arch) groff-1.22.4, but only in the
trivial case where there are no pre-processors preceding troff, in
groff's pipeline, and primary input is from a stream other than stdin.

Okay, that's not strictly true, but .rd will be interpreted by troff,
and will read from troff's stdin, which will be the pre-processor's
stdout; to make .rd work there, you need to arrange for the .rd input to
have been already merged into the pre=processor's stdout, which may be
more trouble than it's worth.
