Call it whatever. If it's so upgradable then why aren't they doing it? There are a lot of flaws that are being ignored and you know it. (A dev, jgarzik, has to put out a torrent for the blockchain instead of pruning it. We haven't solved the 51% attack yet. And on and on) If I see more upgrading going on then maybe my view will change and I will be convinced.
Some of those problems aren't that serious yet, some are being worked on but aren't ready yet... They just announced a request for beta testers for the next version just a week or so ago. There's progress, it's just that compared to bitcoin world's extremely fast pace, once or twice a year doesn't seem that often for updates.
Tell me if this is one of the fixes that's about to be released or if it one of the not so serious ones.
I happen to think this is a pretty serious drawback for adoption.
