Yes.

Stable -- yes, but not necessarily until
the end of all time.

However, what does "at the discretion of owner"
mean above ?

% - unambiguous - distinguishable (two for same object?)

I don't understand the commentary above.

% - facilitate session‐level referrals

An architecture is likely to have multiple
identifiers, often with different identifiers
at different layers of the architecture.

So, while a session-layer identifier might
facilitate a session-layer referral, I do not
think it is a requirement that all lower-layer
identifiers facilitate session-layer referrals.
