Are there any plans to make the PSI a stable part of the product. I understand that the current situation is that it can change without notice or fanfare and that it's not documented or supported on purpose.
However, I love some of the plugins that rely on it and I'd hate to think of them breaking periodically.
Is it time to recognize that the plugins are a significant part of the IDE (as the Plugin Manager implies) and document and support the PSI and manage its changes like a regular API.
What are other people's thoughts on this?
