Is your feature request related to a problem? Please describe.
Since a Deck is personal and belongs to the user that created it (if not owner is changed) and that user are removed (quitting the job or whatever reason) then the whole Deck access becomes forbidden for the other users.

It's too much administration to change owner every time a user are removed, and it's too much to ask for to expect a novice user (that just wants things to work) to change owner before they quit and are removed.

Describe the solution you'd like
It would be much better if it worked like in Circles where the next person in the list of "members" are promoted to owner if the owners account are deleted from Nextcloud.

Describe alternatives you've considered
Sure, one could use Circles and add that as the owner for all the Deck cards, but once again, it's too much to ask for in an organization with 500 ppl. If one of them misses out on doing so, and then are removed, a ton of work could be lost.

Additional context
Question came up from one of our Government agencies in Sweden that are about to launch Nextcloud in full scale now in October.

Start by locating how Deck ownership and membership are handled when a Nextcloud account is deleted, then compare the requested behavior with Circles' owner promotion. Define the ordering for choosing the next member and verify that remaining users retain access after deletion, including coverage for the relevant removal scenario.
