Germany (like a few other countries) is in the situation "too much lockdown, too few sick". So it has to remove those lockdowns. This creates a fun political dynamic where the authorities who just spend a month scaring the population in doors now has to explain and justify why it is ok to go out and get a little sick.
Germany is NOT at a place where the lockdown is too strong. The spread is still growing exponentially and they will run into issues a few weeks from now if it continues at this rate. You can’t keep everything open and then shut everything down once you’re at capacity, as it takes three weeks for lockdown measures to show up in the hospitalization rates.
I don't think the measures will be softened before May, but according to the authorities, the ICU capacity will not be overburdened. Stressed to the maximum, yes, but not (or not much) over capacity.
Another issue is that with an R0 this low there will be a much lower rate of immunity. Which in turn means the restrictions can't be lifted because then the whole mess starts up again.
