This conventional interpretation is the one I'm applying in this question.

I would argue even the 'conventional' definition of 'Tier 1' has been nebulous for long enough that it doesn't really matter much anymore. 

Who a network connects with and how is all that matters, regardless of what label they want to apply to themselves.

The one I think corresponds to the conventional interpretation is "I’m a Tier 1 because I have a SKA peering agreement with other Tier 1 networks and I pay no other network for transit or peering”, or more informally, “I’m a Tier 1 because I pay nobody and everyone pays me, except for my peers.”

This conventional interpretation is the one I'm applying in this question.

Which is unfortunately what some operators serving my region try
applying. And after being contradicted, they move to "regional Tier-1"
speech, which is something nobody ever defined.
