I've been personally using a matrix bridge (self hosted instance of mautrix-whatsapp on a hetzner vps) and haven't opened the main whatsapp app on my phone (other than calls and some rare view-once images) for over a year now and haven't had any issues. While it's possible that this may result in an account termination, I doubt anything will happen if you don't use it for spam/other kinds of abuse
