Observed behavior

For JS/TS files, VSCode dims unused symbols. It's a really nice feature I'd love to have in C++ as well. Would it be possible to add support for unused symbol highlighting to the existing highlighting settings? Even if it's not enabled by default, it would be nice to be able to configure it.
