I would say the contrary. Let's not forget that most of our users aren't hard-core developers (they love Cocoon because they can do complex stuff without programming) and they aren't used to this odd/even versioning scheme that comes from the Linux kernel.

Rather than that, it seems to me that most of the "normal" (i.e. non hard-core hacker) people consider a version without any "beta", "milestone" or other suffix as an official stable release. A well-known example is Firefox that goes through a series of milestones, beta and RC version before releasing a stable version with the same number. Eclipse does the same.

Also, I haven't voted for the renaming Corona to Cocoon 3.0 as I was on vacation, but I really think this is too early. Cocoon 2.2 is just out and we announce a 3.0. This will most probably lead people to consider 2.2 as a transition to 3.0 and just not use it, and thus just look elsewhere.

Stated clearly, I have fears that just as Maven almost killed the developer community for 2.2, announcing a 3.0 now will kill the user community.
