I think the point is to allow PRs that may break the OSX 32-bit build. I 
don't think there are any plans to remove the current support.

In other words, I think it will continue to build and function, but 
nobody will be testing it. So it may break in the future.

And add me to the list of those who do not use (actually never used) 
32-bit OSX. And I've been using macs since 2012. I'm fine with removing 
support.
