What is the correct place to see features supported in redocly-cli opensource version

I am having trouble understanding what features are available in the open-source version and basically feel like there is a need to just test things out.

If I start from the page: https://redocly.com/docs/cli/commands/build-docs

It then links to configuration options on two pages:

1. https://redocly.com/docs-legacy/api-reference-docs/configuration/functionality
2. https://redocly.com/docs-legacy/api-reference-docs/configuration/theming

On the second page it is clearly marked which features are supported in community version with ". Supported in Redoc CE"

But on the first page there is a link to look at opensource Redoc configuration: https://redocly.com/docs/redoc/config

On the opensource version page there is no mention of schemaDefinitionsTagName but it seems to work with the redocly-cli if I just use it.

Then again in the Redoc repo docs directory it is listed in the config: https://github.com/Redocly/redoc/blob/main/docs/config.md

theme: openapi: schemaDefinitionsTagName: Schemas

I can see it in the types desciption too: https://github.com/Redocly/redocly-cli/blob/076784b97e502e5c0ce160bd9ad7a9c685865315/packages/core/src/types/redocly-yaml.ts#L1060

So just wondering how to improve the user experience and understand where to look.

Compare the linked CLI, legacy configuration, Redoc configuration, docs/config.md, and the redocly-yaml.ts type definition, starting with schemaDefinitionsTagName. Clarify which features belong to the open-source version and identify the authoritative documentation path. Done means users can reliably find the supported-feature list and understand this option's status.
