Feature Proposal: Support for batch requests of DocumentSymbols

[Blaiski]

I have a use case where I need to request DocumentSymbol of large number of files on one go for my Vscode Extension.

I have looked into LSP documentation and Vscode's, and as far as I could tell... there does not seem to be a supported mechanism to do this directly. I looked at:

• Document Symbols Request
• Workspace Symbols Request

Workspace request is not useful for me as it does not return the DocumentSymbol hierarchy which is crucial for my work.

I resorted to implementing some sort of batch processing where I go over all the source files I need, sending a DocumentSymbol request for each. The solution works with different languages I tried, but it is far from perfect and I am wondering if LSP community would consider supporting such a feature in the near future?

Considering the performance load it would put on servers, I suppose it could be implemented with some sort of latent response mechanism.

Note: there's a related request on vscode repo.

Any thoughts or tips, please?

Thank you
