This is already what we are doing. But if such a case should turn out to be contentious, we would discuss it even after someone marked it as eligible without discussion. At least that would have been my expectation. So if we want to make such a detailed policy, could we please add that as well?
What does this mean exactly?
Ok, this is our current issue with Lingua Franca Nova and Ancient Greek. Shouldn't we better discuss about the underlying policy regarding constructed and ancient languages? A general rule seems better than the possibility to allow everything by a majority vote.
I don't recall that we ever discussed allowing projects with BCP47 codes. Again, isn't this something that should be discussed as a policy?
The combination of 3.1 and 4.1 would be bad insofar as it allows a 2/3 majority to introduce a new member anyway.
But apart from such strategic trickery,
I'd like to comment on the main issue:
Yes, Langcom works with the principle that a proposal is approved unless a member is against it, in which case the proposal dies (it is not exactly rejected, n'est-ce pas?).
At times I have been quite annoyed by it as well. I think however that in general it works quite well. Over the course of the years in which I have been a langcom member now, I sometimes thought about whether the “governance“ could be improved. But my personal conclusion always was: not really. It wouldn't harm to formalize a rule for getting rid of a theoretical trollish member opposing everything without a reason. But apart from that? I'm not really sure that introducing majority voting will help much.
