I think the reasoning is the only CI things that get bundled into an official release version are iron-clad and extensively tested stuff that you would want immediately.
I keep looking to see if there is an update for CI and of course there isn't, but it made me realize - I like not NEEDING to update CI. There's nothing I've found missing that would be solved from an SVN copy, and if there was some new feature I wouldn't know about it because the online docs don't reflect it yet. Its a pain to update when you are responsible for making sure nothing breaks on complicated systems - have to make sure all my Curl, XML, Encryption, and ORM extensions still work under the new CI, make sure my own code works, etc etc.
It seems that this is something that is done for a very good reason, even though for sales/marketing purposes its perhaps not as good.
Its not really important, but it makes me feel a tad smug. I use a framework that doesn't need gimmicky sales tricks or endless updating and patching. Much like PHP itself - some people still use version 4 and think its just dandy. I only update it regularly because I have to for security compliance, but I don't really 'need' to at all. It just works.
Its in keeping with with the core CI philosophy, which I think this is more a matter of carefully weighed intention than marketing oversight.
On the convenience side though, I think it would be nice if some nice person had an automated system where you could just click a link and get the latest daily build of CI, 'bleeding edge version', for those that want it.
In a sick way I'm kind of glad there isn't on the main site, because it illiminates my temptation to use something that isn't thoroughly tested.
Oh, the other nice thing with few versions is you might notice that no one asks 'what version are you using?' Its just sort of assumed we all use the same one, unless a person just recently updated and is now having a problem. If they use SVN they know full well something might break, so they probably have some system in place to deal with that.
