Is this valid though?

assumeSafeAppend is an unsafe function that *requires* no one else have a view
on the items after the end of the array.

Just the same, you will overwrite the old items, without destroying them, nor
assigning over them.

I think this is just an unsafe function that was used wrong. The result is
simply undefined behavior.

I think it would be a needless restriction to not allow assumeSafeAppend on
immutable (and const).

This seems invalid to me.
