Having a framework how different datastores conceptually fit together
is essential for getting implementations that behave in a predictable
manner. I am not talking about an implementation framework. As long as
people use key terms with different meanings, I have little hope that
this leads to interoperable behavior.

I think a client needs to know what it means to modify a certain
datastore. A client needs to know what validation means. If people
code against <running>, <indented>, <applied>, <ephemeral> (and there
are more suggested) and it is undefined how things conceptually relate
to each other and interact with each other, then I have my doubts this
will lead to interoperability since systems likely expose rather
different behavior.
