Given that my graduate work was an email gateway system, between 
independent, heterogeneous services, no, I would not say all.

However meaningful heterogeneity essentially requires losing some 
information, so I'd say 'preferred solution'.

Since I was not involved in any of that work, my response is based on 
comments from others.

My understanding is that the design model then and now is a homogeneous 
service, on top a variety of heterogeneous services. Hiding the 
differences by providing a common service on top of them.  That the 
common service was originally specified as one layer and evolved into 
two does not change the meta-design approach.
