I don’t think so, but I wouldn’t be surprised if, as the old world order continues to change into… this, that we will see an expansion/rework/new layer on top of the current association agreements. Something more like associate member states.

My guess is that it will take a form where associate states will have no explicit political power (no elected politicians, and not likely any appointed political positions either), but will have greater access to less direct influence, that could potentially-eventually even include formal rights of hearing with the Commission, a right to speak in Parliament, and/or guarantees of consultation on certain matters.

I think this could become a more standardised system than the current association agreements. In many ways it would be like having different membership tracks, with different benefits and requirements. I expect that realist school foreign policy is going to overwhelmingly dominate global foreign affairs, with the idealist school being relegated to mainly having influence in regional foreign affairs. As such, I think standards on political and human rights that these associate members will have to live up to are going to be an order og magnitude less strict than what is required of full members. There will probably be other requirements that will be more important, such as certain foreign policy commitments.

As for level of integration, I would imagine that such an associate member would be able to become fully integrated in many areas, but on an opt-in basis, possibly with almost standardised package deals, where certain benefits and obligations (both legal and economic) are bestowed together. Things like Schengen membership, or access to some of the large redistribute programs (agricultural subsidies come to mind) will remain very exclusive, and membership in these will continue to be largely political, rather than something that can be accessible to any associate member that fulfills certain objective criteria.

Do I have any special insights that make me able to predict the future? No. No one can predict the future. But I think these are some pretty solid guesses.
