[REQ] List of generators that will first support openapi 3.1.0 features

Is your feature request related to a problem? Please describe.

This ticket is a record of which generator will first support opeanpi 3.1.0 specs and feature

The issue tracking 3.1.0 spec support is here: https://github.com/OpenAPITools/openapi-generator/issues/9083

Note:
One could track the supported features by adding features to our supported feature matrix like we see here:
https://github.com/OpenAPITools/openapi-generator/blob/master/docs/generators/python.md#schema-support-feature
It may also be useful to run unit tests specs on generated servers/clients like python does in these 3.0.3 json schema tests.
Which run on node4 here

For generators to be able to implement 3.1.0 unevaluatedProperties they need to have properties, patternProperties + additionalProperties working. Not all generators have additionalProperties working for all schema use cases.
There is a java property supportsAdditionalPropertiesWithComposedSchema which indicates broader support for the addditionalProperties keyword on composition use cases (which are usually type unset=AnyType schemas)
The generators which have this set to true are:

• python
• python-prior
• java

Generators

Please vote on Generators that you want

Please vote on generators that you want added by adding +s to the generator name in a comment.

If you want a feature, how about you write a PR adding it?

This is an open source project, so if you want a generator to support the new features please consider writing a PR adding the feature that you want. We are all volunteers here and we can all improve and contribute to this project.

Start by reading issue #9083 and the documented Python schema-support feature matrix. Compare generator support for properties, patternProperties, additionalProperties, and the referenced 3.0.3 unit tests. Done would require a decided generator list or updated tracking documentation, but the issue does not define a concrete implementation scope.
