That sort of diagnostic is likely produced by a YAML plugin, which uses a schema from https://github.com/SchemaStore/schemastore.

I do file a SchemaStore issue once per clangd release about updating the clangd schema, here's the one for clangd 19: https://github.com/SchemaStore/schemastore/issues/4022.

If you'd like to file one about `DefaultArguments` sooner, or even submit a PR, please feel free.
