I agree with the result of your logic (I really want them to get the firmware right).
I'm perplexed that they use many brand new customers who happen to be in Europe or happen to have certain features (PDC, Winter Package) as guinea pigs and don't allow those of us who know their cars and would LIKE to be guinea pigs to test 5.0 as well. But that's a company decision and I can live with it.
What I don't agree with is the last sentence. Vampire drain is a massive issue. ~3kWh a day, 1000kWh a year that's actual cost. Also, cars parked without charging for a few weeks are possibly being bricked (an S60 would be a 0% SOC in about 3 weeks). Also, if you travel and don't have a charger right at the place where you stay (many hotels offer no place to charge) then you'll lose 5% of your charge a day in your S60 - that can cause you to get stranded on your way to the next charger.
So yes, I don't think they should roll out a buggy release, but I also think that vampire drain is much more than just a nuisance. It's a reasonably serious flaw.
This. Vampire drain is a huge issue in relation to cost and wasted electricity.
Also, I have heard the opposite regarding 5.0 - that there are not many bugs and the beta testers confirmed the latest release .102 addresses the bugs with cars not waking from sleep mode. That's just what I've gathered by following this thread and reviewing the bug tracker wiki. That plus the fact that Tesla is confident enough to include 5.0 in new deliveries.
