Sounds better. Note that while fdset-id is optional in QMP, I think it
needs to be mandatory on the CLI (you're telling qemu to use an
inherited fd, but unless you know what set that fd belongs to, you can't
then refer to that fd elsewhere on the command line, and unlike the QMP
command, there is no venue for QMP to tell you what set was autocreated).
Bike-shedding: I think the command line can be slightly shorter with:
-add-fd fd=24,set=1,opaque=...
with no real loss in information (that is, s/fdset-id/set/), since our
command lines are already quite long. But going longhand to match QMP
doesn't hurt my feelings (libvirt will be automating this all anyway, so
I won't really be typing it by hand).
