I'm closing this because it is not a good way to solve this. IMO, a good approach would be to let users write the diagnostic severity they want to have for all or for specific diagnostics groups in their clangd config file (like described above). I've opened clangd/clangd#1937 to discuss how to move forward with a better plan.
