† Depending on how you (re)start vscode (terminal vs launchd) it's going to either have some project env vars or not. e.g do `code /some/path` in a terminal and it inherits env vars from the terminal, which is nonsense on macOS because then if you reopen the project the env vars are gone because it's been relaunched by launchd. Dunno if it has been fixed but it was even worse when a vscode process initially started via terminal would have env vars inherited for all subsequently opened projects, even different ones.
