Spot on! I almost started a thread once on MA vocabulary translated to RL timescales - we could still do that .Wouldn't fret about the authentication system.
MA used the word "gradually". Considering updates that they deem urgent and immediate regularly land in the "years" time scale, I wouldn't expect the GC to be phased out before 2020.
Also back to positive: of course thanks for actually providing an address for us to have our opinions on.
The repeated timelines on Compet and beta hopefully mean we really get to test it in just a matter of weeks, possibly with proper connections to EU via stables and other unknowns...
