Hi, community, this is the latest RFC about

Binary IDL With MessagePack Bytes

, previously known as

JSON IDL

. (Discussed with @thankful-minister-83577 and @high-park-82026) In summary, this proposal will 1. make our experience about

dataclass

and

Pydantic BaseModel

amazing. (100% correct with their type) 2. solve the 2 different `dataclass` ambiguous errors in propeller's compiler. I know this feature has gone through a lot of back and forth, so thank you all for your patience. Please take a look, and thank you, everyone. https://github.com/flyteorg/flyte/pull/5742 cc @cool-lifeguard-49380 @damp-rain-31363
