I'm getting an error about not being able to allocate the client:

$ sudo ~/bin/qmicli -d /dev/cdc-wdm0 --dms-set-fcc-authentication
--device-open-proxy
error: couldn't create client for the 'dms' service: CID allocation
failed in the CTL client: Transaction timed out

Google results on this error seem to be very generic, not really sure
what to even start with debugging that. Could this be some kind of
mismatch between my ModemManager and the custom qmicli binary?

I'll go ahead and try installing this in the next few days I think.
Sadly it doesn't look to have been packaged for Fedora 20 yet(?).
