Point 1. is indeed a "uncomfortable" part of dojo. Getting started is difficult. For a lot of demo and hello world like apps CDN version is fine, assuming they are only using the modules packaged into dojo.js on CDN. If you start using other modules, then you will soon see a escalating number of HTTP requests, and for this reason using CDN version for production is bad idea.

Its just not that easy to get started with and get a sane production build from dojo yet. Hope all of this will change by the time 2.0 is out.
