I'm using the stock python 2.7.9 from Poky/Yocto master:901be2cb69892595443ed41ab4be285932db15eb

Is there an answer for this that's a bit less intrusive?
Perhaps there could be a DISTRO or even IMAGE feature to
enable/disable this checking?

The pep you referenced mostly talks about why this was changed
and how to disable it - manually within the python code itself.
What I don't see is where/how/what to change/import to actually
let the full certificate checking happen.
