You could add a couple of lines to the build code and it would not be possible to build 32-bit, so that is a necessary but not sufficient condition to claim to implement the JEP IMO.

I'm not looking for one big PR, I'm looking for multiple PR's as proposed but which all fall under the JEP umbrella. Until the JEP is targeted then nothing can be integrated anyway. This is what, I thought, dependent PR's were designed for.
