Should we deprecate the pydantic plugin https://github.com/flyteorg/flytekit/tree/master/plugins/flytekit-pydantic (pydantic v1) given that 1.14 introduced an official base model type transformer using the new messagepack transport?

Yes we should

Do we have a process for this? Do we just remove the plugin from the repo and stop publishing new versions?

Do we have a process for this?

Not really, but I'd try to phase this out like, in the next release, deprecate it, and remove it in another release; just to give it some time to users to move away from it. wdyt?

in the next release, deprecate it

https://github.com/flyteorg/flytekit/pull/2792 added the warning log message “The Flytekit Pydantic V1 plugin is deprecated.” in october which was part of the recent release. Does this mean we can delete it now already?

but we should just delete it, it never worked right @damp-lion-88352?

yes it never worked
