I agree with Aaron that the actioncolumn is too far right at the moment.

This one feels slightly surprising to me from a user perspective as I
can't edit the actual mapping here. But it is cleaner and I guess one
could argue in the opposite direction too.

It does involve a bit of clicking when it's only possible to add one
node entry at a time, but I'm not generally opposed to the current RFC.
I can image the action column takes a bit of getting used to as a
Proxmox VE user, because we don't really have those there yet.

The full grid might become quite big/confusing and involve lots of
scrolling or how would the grouping by node be done?

Maybe a third alternative would be to have a tab for each node and show
basic meta-info like how many devices are already selected on that node
and a warn/error indicator if that node is affected?

Would the full grid and tabs approach even be feasible with many nodes
or require too many API calls?

AFAICT, this always evaluates to false, because of the misplaced '!'.

IMHO, Add mapping was/is better

Nit: Is it even necessary to return these two as they are already
persistent properties?
