Not all modems are PPP. The IP layer handling isn't the responsibility
of the modem manager, it's the responsibility of the connection manager,
since the conneciton manager applies the IP-layer policies and such.
There are a number of different IP configuration methods that modems use
these days: PPP, static IP, and DHCP. It makes no sense to put PPP
into ModemManager without putting the other two in as well. But putting
the other two into MM is clearly expanding the scope of MM way beyond
what it should be.
