Is that wwan_hwsim integration to be able to create fake modems in
userspace that are exposed via the new WWAN subsystem? If so, wouldn't
they already be supported by the current ModemManager, which supports
the new WWAN subsystem?

Please correct me if I'm wrong; openairinterface5g allows you to
simulate/implement the radio and 3GPP protocol side of a UE. But there
is no AT/QMI/MBIM control protocol implemented in openairinterface5g,
or is there?

That would be very interesting indeed.
