> Tibet was a theocracy with a religious leader for a while until recent times.

Yes, but it was still like contemporary Iran - a country which happened to have a theocratic system of government, not a country whose sole raison d'être was to endow a religious group with the trappings of statehood.

> Also I think the Albanian plan is more on the lines of Mount Athos: it is technically an in independent administration with independent (monastic) government but still part of the Greek state

I don’t believe that is true - if you read Albanian PM Edi Rama’s statements on the topic, he always cites the Vatican as his inspiration, not Mount Athos - which makes sense given Rama himself is Catholic, not Orthodox. He isn’t proposing this idea out of any personal belief in Bektashi Islam… a cynic would say he is doing it because it is good PR both for his country and for him personally… he’d surely give more high-minded explanation, in terms of the Albanian state giving a magnanimous gift to the cause of interfaith tolerance and religious moderation… but definitely the model is the Vatican not Mount Athos
