I’m always hopeful, but there was another state/city in Germany (Munich I think?) that tried to do this a long time ago, then after 10 years of not being able to move entirely over, they moved back to MS, then I think they tried again. Really flip-flopped a lot. I think stuff like this needs to be more organic in its movement rather than big bangs and milestones. Just let it creep in and take over.
It’s fairly important to keep it private for US citizens, see here.
