This was basically my opinion, with the feeling that SOA is much more
generalized a concept than REST, and as such SOA is useful for
diagramming the operations of a business only some of which might
relate to REST or be implementable in such an architecture, but from a
technical viewpoint to talk of REST for any particular solution is
more productive for understanding that solution because REST is less
generic (if the specific requirements of REST do not meet the
architectural needs of the solution this is also productive) whereas
talking of the more generic SOA specific to technology for me as a
technician doesn't tell me much.

I had never even considered this.
