Yes, the new version of PolicyKit is a complete rewrite and the software
architecture is very different from that of PolicyKit 0.9.x.

Anyway, since you can do everything you need (as an user of PolicyKit)
through the D-Bus interfaces or supplied command-line tools, the LGPLv2
license should not be a concern since process boundaries are involved.
And, just FWIW, I  don't consider someone using the PolicyKit D-Bus
interfaces to be a derived work of the PolicyKit daemon.

If you are writing extensions to the PolicyKit daemon (such as a backend
or information provider) then these extensions will need to be LGPLv2
since they arguably are derived works of the code in the PolicyKit
daemon.

Hope this clarifies.
