We can potentially deal with the more conservative part of the user base on the redistributor side - so long as the PEP says it's OK for us to not apply this particular change if we deem it appropriate to do so. That would make this a case of upstream asking us to do the kind of risk assessment that people pay us for, which is a kind of request I'm generally happy to get :) That way, if downstream users get upset, we can point them at their vendor support department, rather than having them take out their ire on upstream volunteers. Also, after thinking through the implications a bit more, my guess is that Fedora & Software Collections will accept the change without any fuss, but the CentOS/RHEL side could be a more involved discussion. On the other hand, orgs with these kinds of problems aren't likely to have rolled out RHEL 7 or CentOS 7 yet either, so they're probably still back on Python 2.6 (RHEL 6) or even 2.4 (RHEL 5). 2.7.9 is going to be a somewhat "interesting" release that requires careful attention anyway (due to the completion of the PEP 466 backports), so if Guido's OK with it, sure, let's kill the "HTTPS isn't" problem for Python 2 as well. One additional wrinkle in that case: we will likely need to backport the SSLContext related changes to httplib as well. Cheers, Nick.
