The main reason for moving this stuff into user-land is that PPP is
getting somewhat bloaty (there are 7 compression methods already
published as RFCs, plus layer 2 tunneling, plus multilink, plus
encryption, plus LQM - all of these would need code in the kernel for
a mostly kernel mode implementation).
