Honestly, I am allergic to all this media hype around a simple Google form. It doesn't change daily life that 78 people filled out a survey; a sample so small and self-proclaimed doesn't prove anything about real behaviors. Identity documents, especially for travel, are not a matter of habit but of legal compliance.
Just because someone checks a box doesn't mean they act accordingly in front of bureaucracy and strict rules of immigration, like when you have to prove your address for Anmeldung.
