IIUC the new option may be implemented subscriber-side and/or publisher-side and/or both, and the subscriber-side option may be "enhanced" in future to prevent cycles. And probably there are more features I don't know about or that have not yet been thought of.
~~ Even if the plan is only to implement just one part now and then add more later, I think there still should be some consideration for what you expect all possible future options to look like, because that may affect current implementation choices. The point is: - we should take care so don't accidentally end up with an option that turned out to be inconsistent looking on the subscriber-side / publisher-side. - we should try to avoid accidentally painting ourselves into a corner (e.g. stuck with a boolean option that cannot be enhanced later on) ------ Kind Regards, Peter Smith.
