The question is whether you would be able to recognise it when it happens.
I don’t see how passwordless root affects that. It can actually make it even less recognizable as you won’t even know when a process runs a sudo etc.
But what if you didn’t trust any monolithic kernel system?
Questioned that in another thread too:
What if you thought XEN was outstanding and unique in its own way?
What then?
Meanwhile, you’ll have to choose something that people can work with.
But we are not discussing functionality of a beta system. That “meanwhile” has continued for many years and has become a status quo.
