I shrunk down the interactive (with server-side or external functionality, like third-party comment-boxes) features my sites a lot because of being worried about GDPR, basically killing a small community and having a direct negative effect on users. The overhead/worry is real, even if as a consumer I'm a big fan of it. The toolchain/conventions may eventually catch up so that things are GDPR-compliant by default, but the downsides are still very palpable. [ And even with all of those cutbacks, I'm still not really compliant on all my sites... (legacy software/not knowing what exactly my data server is logging/etc.) ] But, as a direct answer to your question: I don't think many things in principle are impossible with the current privacy laws. But that doesn't mean it's not having a chilling effect.
