Is that a work in progress constraint, or is it the intended long term 
behaviour?  (I'll try it out shortly in any case.)

I ask because currently, if a package is explicitly stated as a build 
dependency, then with `strict` confinement it's automatically included in the 
final snap where necessary.  What makes `classic` confinement unable to 
automatically handle the inclusion of build dependencies in the same way?
