But OpenWrt covers both devices with and without enough RAM and flash,
so keeping both makes sense.  You do need a few MBs for MM with friends,
while umbim + uqmi is in the kB range:

I guess it's time to add more libmbim/libqmi compatibility to umbim and
uqmi. I added support for the mbim-proxy to umbim a while ago:;a=commit;h=ff8d35615153086f4b89443e511907f10ff059de

My main usecase was testing umbim on my laptop without affecting normal
ModemManager usage, so I disabled it by default.  But now this feature
is relevant for OpenWrt devices too, so maybe we should enable it there?
And do the same for uqmi too?

You still have to be careful not to mess with the settings ModemManager
is using of course, but I find it very useful to be able so send an
occasional umbim request without stopping ModemManager first.
