Yes, a user status/right “deceased" is IMHO important. It was also the reason why I expected a SUL policy to be created soon or later. I tried two or three time to raise the issue since 2016.

Now some projects block accounts, but it's not a standard process. It has to be fixed soon or later. At the moment, a relative can reuse an old account in theory on another platform, if they wish to do so. For example I find archive of images of my deceased partner and despite the user being blocked on a local wikipedia, I start to upload them on Commons in their name. Everybody has their way to cope with grief. Do we accept this or not?
