Liam,
as I think the members of the GC invest simply more time into any given issue than the average member, I expect them to be maybe a bit wiser.. I wish we had accepted the last TA, and as far as I remember the majority of the GC was indeed willing to accept the offer. I believe referendums are in general at risk to be mainly influenced by public sentiment rather than reason, see e.g. Brexit or Trump.
Having said that, I believe the future of the AOA is crucially attached to a fair and balanced composition of B and C scalers. If the GC is simply controlled by the majority, all future decisions are at risk of being biased toward C.
