I don't know much about WebGL and WebRTC specifically, but sometimes it's just inherent to the feature, and it's literally impossible to implement it without allowing fingerprinting the user.
For example, your screen resolution/viewport size can also be used to fingerprint you. It is impossible to allow adjusting a website to different viewport sizes without leaking those viewport sizes - the only way to restrict fingerprinting is to not offer the feature of using arbitrary viewport sizes (which is what Tor browser does, for example).
Yes, it's all a trade off of functionality for privacy.
