Thoughts on getting rid of

Optionable

as a separate thing and merging it into

Subsystem

(now that the latter is the only

Optionable

) Vs. keeping those as separate concepts? Would require moving

subsystem.py

to

src/python/pants/option

.

Please do! I would love to see this. Imo, our options system is pretty complex. Powerful, but complex. Refactoring like this will make it easier for us to do something like re-invent options to work with MyPy automatically

the only “not currently working but should probably be revived” thing is scoped subsystems.
