It’s been 6 months but last time I checked neither IntelliSense nor clangd worked with modules. The build tools have been just about functional for a while though, you’re right.
Yeah, Intelisense is a bummer, but you really need VS proper, nor VSCode, which I assume given the clangd reference.
Whereas one kind of works (VS), there is apparently no work going on VSCode Intelisense, ticket is stalled since January, and the promised announcement never came up.
