The upstream language server (clangd) has some support for this as of version 17 (Sept 2023) and provides inactiveRegions annotation.

Inactive regions is a clangd LSP extension, but does not appear to explicitly documented in the clangd LSP extensions on their website. So basically this issue is a request for us to consume those annotations and add the ability to style them appropriately (grayed out) to match the behavior of other editors.
