Excuse me, could you clarify, if my understanding is correct?

Assuming that a user is using 2025.3 of….

~~PyCharm /~~ IDEA OpenSource Version: NO compatability with plugins relying on the LSP API.

Unifield ClosedSource ~~PyCharm /~~ IDEA without ever having had a paid subscription before: Compatability with plugins relying on the LSP API ← ???

Unifield ClosedSource ~~PyCharm /~~ IDEA Version with an active paid subscription: Compatability with plugins relying on the LSP API

Thank you very much!

Edit: For PyCharm this posts seems to clarify my question: [Update on LSP and Template Language APIs in PyCharm](https://platform.jetbrains.com/t/update-on-lsp-and-template-language-apis-in-pycharm/1453)
