I assume the 'original Hob' compatability will only be maintained until
Hobv2 is merged?
Is there anything preventing us from having an optional parameter on
generateTargetsTree to switch to pro mode rather than duplicating a
bunch of code and functionality on a temporary basis?
something like:

> + """

Then you can use the resolve boolean to switch the generateBlahBlahBlah
methods to operate in the old or new way. Method signature would be
something like:
> + def generateTargetsTree(self, klass=None, pkgs=[], resolve=false):
> + def generatePkgDepTreeDataPro(self, pkgs_to_build, task,
resolve=false):
