I had several reasons when I've suggested this approach. Firstly, for versions like 2.0.0-alpha I would expect to get 2.0.0 (without -alpha) soon and without major changes. This won't be case for Sqoop as we might need to do major, backward compatibility changes - it's undesirable to introduce backward incompatible between minor revisions. We also most likely will release several version before leaving alpha state, which might cause issues to see what is and what is not considered stable. Also this first cut is very far from something that might be called Sqoop 2, it contain just very basic set of functionality without several most important goals of Sqoop 2. However I'm aware that Hadoop is following this path .
Please note that I did not invented this idea. For example KDE project  is using very similar approach for quite some time by now as you can see on their archive . Versions like 4.8.90 or 4.8.95 are "pre-releases" for 4.9. Another example would be Ubuntu one client . I would recommend taking a look on my original proposal as it contains all the information .

My motivation to provide early bits is to get feedback from actual users as soon as possible, so that we can incorporate good ideas before it will become too expensive.

I believe that this version number implies that it's very far from current stable 1.4 version and very very near to 2.0, but it's not 2.0 yet. I would also like to volunteer to be the release manager for this first cut of Sqoop 2 branch.
