It's likely to be partly complete by 2.8.9, but I don't know how much will 
still remain to do.

The main reason to put the plan on the wiki page instead of just doing it as 
a lone ranger myself is to facilitate parallelization of the tasks.

The plan will probably have to be finished first. It's likely that we'll end 
up aiming for linking targets together (target_use_targets instead of 
target_use_package), and I think that part is actually achievable in 2.8.9.

"plumbing API" is low-level API (eg calls to set_property)
"porcelain API" is high-level API (eg calls to target_use_targets)

Thanks,
