This is precisely it. If an integration mechanism can't be implemented as a clear and uncomplicated library that strongly encourages correct use by making it the path of least resistance, it probably isn't any good.

(And note that I said "library" rather than "framework". This is important as libraries are more like a thin layer of glue while framework is more like a metastasising cancer)

Most of the time, REST, strictly speaking, demands too much attention even for relatively simple stuff, and therefore is not a good integration technology. However, some adaptations of REST are.

The one thing that is a bit sad is that there is some nomenclature confusion. These days a REST API doesn't refer to Fielding's vision, but a more practical adaptation of the mechanical bits of it.
