While meetings to discuss what *other* groups are working on so that there is better communication of what is already happening could be useful, I cannot see the Che engineers participating. We are already stressed on meetings.
What would be immensely more useful is a foundation mandate, ratified by the architecture committee, the board, and the affectect projects to require the various projects to collaborate in a certain way, at the cost of being disallowed from releasing unless certain interoperability standards are met.
In the case of the language server protocol, it could be:
1. Minimum, common support for protocol implementation across products.
2. Implementation of a shared language server repository that is hosted at the foundation
3. Packaging of what will be 15-25 language servers for accessibility locally and in distributed systems
If this sort of mandate existed, and there was some carrot and stick behind it, then having a committee to manage the effort, report on it, and enforce the various gropus on it to move it forward, then things get interesting.
