I would keep this. Or maybe we can clarify it? I don't know what is unclear
actually.
> might have unexpected effects
Someone might except duplicate UUIDs to work, and a "uniqueness constraint
violation" would be unexpected for him.
> Manually adding a property with the name jcr:uuid to a non referenceable
I'm not sure what is the motivation for this issue. Do you plan to add such
properties?
> doc: clarify warning about setting jcr:uuid on non-referenceable nodes

> But the tests for OAK-11000 show that this just works as "expected in Oak"
> (throwing an exception even though no mix:referenceable is present) - as the
> UUID index is maintained even for nodes that do not have mix:referenceable.
> Should we remove or rephrase that warning?
