If you use Proposed APIs you can't publish your extension on the Marketplace and your user needs to run a fork of VS Code, or the nightly build. Either way, your user loses access to the Microsoft closed source extensions which are DRMd to only work with official VS Code build. Like the remote development extensions I mentioned, Pylance, GitHub PR commenting etc.
Also, sticking to existing APIs is an inherent disadvantage when Microsoft can add whatever APIs meet their exact needs. Nobody could build Remote Development or Live Share until ms did because the APIs didn't exist.
