Very nice work-up, thanks!

<shameless-plug>
However, you didn't include XML -- which, while absolutely horrid, can 
be quite readable with the appropriate preprocessor, such as xaml [1] 
</shameless plug>:

     ~schema
         // optional
         ~version: 1

     ~bootstrap
         ~requirements
             // Temporarily commented out 2016-01-10
             // magic-build-helper
             ~setuptools
                 ~version: >= 27
             // for the new frobnicate feature
             ~numpy
                 ~version: >= 1.10

which ends up as:
