see the PR description here: essentially i want to use the v1

Payload

object to encompass what we use

TargetAdaptor

for currently. because

Payload

was always intended to be a correctly-hashable bunch of data, i think

Payload

instances have all the properties we want from

@dataclass(frozen=True)

objects (they even have their own freeze method!) https://github.com/pantsbuild/pants/pull/8760

that is not what the linked PR does, however, it does something much worse

but the message above describes what i think we should do

i can extract it out into its own PR and give a good overview to make it easier to discuss

i think it would be a great idea to sprint and do that right now before dinner

attempted to bridge v1 and v2 target classes here: https://github.com/pantsbuild/pants/pull/9188
