Sorry haven't read the full thread.
But you don't have the full story here at all. I live in Germany. We've had "3G" ruling for months (must prove vaccinated, recovered, or recent tested status) for things like indoor dining, soft play, sports centres, hairdressers.
All that's changed is that they have changed some of these to "2G" now which is vaccinated or recovered - no testing exception, except for people exempt from vax (including too young/recently pregnant). That's dine-in restaurants, pubs, venues, hairdressers etc. This is the "Unvaccinated ban" that the newspapers like to talk about.
They have also increased the 3G regulation to also cover non-essential shops. There's no suggestion that essential shops will ever need any kind of requirement for entry. And even non-essential shops are free to access for anyone with a recent LFT.
Public transport is changing to 3G. I don't really agree with this but it's not going to 2G.
Some venues will change to 2G+ which means you need to be vaccinated, recovered or exempt WITH recent test (for everyone). This is mostly places like hospitals and care homes.
