Notably it’s a per-user backup which can be a no go for shared computer. But it’s the logic Apple is pushing for years now. iOS devices never got the possibility to be shared because they are considered "personal". And this is also a no go for some people (I think this logic is ok for phone but more discutable for iPad). By this logic a backup fall into the personal category for Apple so you need an undividual account. Which again make senses in some way. Because with physical backup, if not encrypted, anybody that put his hand on the disk get access to all the data of all the users. Usually you trust people you share a computer with more that any company, so maybe it’s pushing the logic too far to force use to get an iCloud account. But from a practical standpoint you can’t either say it’s useless. Kid grow and get his own computer? Just setup iCloud on the new one and he get back all it’s stuff painlessly. Your shared computer crash and you decide to buy two laptops to replace it? Easy to split accounts. Everything is already easily doable using the migration assistant, assuming you have a backup, but can be easier in the futur for the proverbial layman.
