@conda/steering-council comments welcome!

From https://github.com/conda/ceps/pull/81#issuecomment-2725756535:

Also please call the existing format v0.

My understanding from meta.yaml vs recipe.yaml was that v0's were not standardized ever. That's why I am/was using v1 for environment.yml in https://github.com/conda/ceps/pull/81.

Happy to change that assumption though. I'll drop some comments here for clarity.

[jaimergp]

Also, conda-lock is already using v1 vs v2: https://github.com/conda/conda-lock/tree/main/conda_lock/lockfile.

[jaimergp]

And same with repodata.json, never standardized but the current code in conda distinguishes between versions 1 and 2: https://github.com/conda/conda/blob/9eb05d85702aa78fd3793b840d79a910764544f1/conda/core/subdir_data.py#L264

This language is supported by CEP 15 too.

[jaimergp]

Aaand more examples in this search. paths.json versions are 1-indexed, and so are content-trust signatures.

I think we are going to have trouble accepting such a long list of exceptions for this CEP.

My current opinion is that meta.yaml is v0 because it was never and will never be standardized properly given the complexity of the schema, Jinja and selector features. But in all other cases so far, the opportunity for v1 versioning via a proper standardization process is feasible.

[beckermr]

Oh no :/

[beckermr]

OK @jaimergp. I reversed the logic of the CEP and went with existing things as v1 with an exclusion for recipe formats.
