I'm happy to add this if there are any pointers on what's needed.

thank you @vdemeester for raising this issue.

did some exploration on the code base and related v1 docs..

• mainly the script.go, parse.go, and task_validator.go are coded with the v1beta1 objects, like *.Task or *.Step.
• tried to flip the version as v1, the current unit tests pass still because there is no diff for validated parts of the fields between the 2 versions, like script or img. (I referred here https://github.com/tektoncd/pipeline/blob/main/docs/migrating-v1beta1-to-v1.md)
• one exception is parser.go - there are *.Task and *.ClusterTask. as I checked the current pipeline configs, the *.ClusterTask is only on v1beta1.

thinking likely we need to support validations for both versions, I should not just flip the version in the code. perhaps we need to implement and structure the code, somehow like the pipeline https://github.com/tektoncd/pipeline/tree/main/pkg/apis/pipeline - so diff folders for the v1 and v1beta1 versions...
also, we might need to implement new rules for the updated v1 api.

some initial thoughts, how about your ideas?

hi @vdemeester, wave my hands here ;)

any more contexts perhaps we could have here. we are trying to update the v1beta1 reference to v1, but met the question likely we will still need to support the v1beta1. also we are not quite sure what will be validation rules updated here between the 2 versions.
