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.
