Unless there is spread spectrum in ROS you cannot use it. Of course, you
can use the part that is not spread spectrum, but the FCC is not going
to issue a blanket approval for ROS if any part of it is spread
spectrum. They are not interested in issuing approvals for programs
anyway. They just said that ROS was spread spectrum when asked and
spread spectrum is not allowed under 222 MHz, and had the ARRL
communicate that.
As a ham in the US, you simply may not emit a spread spectrum signal on
HF. It is your duty to ensure that you do not, however you go about it.
It is not the FCC's job to tell you what program you can use. It is the
ARRL's job to interpret the regulations if asked, which, in this case,
it is illegal to use ROS 16 or 1 baud on HF, or any other variation that
is FHSS.

That would mean if you would implement ros or similar in a multimode
soft like multipsk or dm780 you would not be allowed to use it (the
whole soft) in us ??? I think if only a part of the soft is forbidden
to use (on transmit) all other modes can be used
If for instance rtty was forbidden in germany but no other mode I can
use all other modes in a given software
So if in us ros hf is forbidden (but not ros mf) you could use it in
us ... right??
Just my understanding of laws ,, but I may be wrong
