That's an idealistic argument. Sometimes you just need to delete things and there's no negotiation possible.

Whether that makes sense to you or not as an engineer or scientist doesn't matter much. There are tons of things that humans want that "don't make sense" but that you need to conform to regardless. A great example of this is typically the law.

"Immutable" does not preclude deletion, that's what I'm saying. Indeed, to delete something can simply mean to publish a new version with no content. If there's no reference to the old version, it will get 'garbage-collected'/ 'forgotten' by the system.

That has nothing to do with physical reality - it's only about feature set of human-designed systems.
