As multi-root workspaces become more popular and widely adopted, it would be great if vscode-clangd could support this as well.

There are many use-cases for C/C++ projects where this would be useful (working with different hardware targets, working across third party libraries, etc.). I imagine there would need to be a fair amount of discussion on how to approach this. Some items for debate are whether the plugin should spawn an instance of clangd per root or whether it should be allowed for the client to specify multiple compilation databases.

Some relevant links to study on the LSP side are the vscode LSP multi-server example which illustrates how to start a server per wokspace folder, and the LSP specification for handling workspace folders. Feel free to discuss below any ideas for how to implement this!
