I guess it’s OK. I mean, I expect the internal healthcare message system of an entire nation will be NOT federated with any external server. I think they (imho reasonably) don’t need and don’t want any kind of external federation. This is a good thing anyway, they are dropping proprietary and centralized protocols to something further controllable and completely modifiable. A fork where expected, of course, according to internal needs; imho the only thing that’s important is staying FLOSS
