YES. This for me is *exactly* why it is so infuriating. And doubleplus 
regarding security. Followed closely by something installing the py-27 
version when I wanted the 36-version.

I'd like to have the latest stable python for everything that requires 
it. Like I have with perl. I think that means py-36. I don't want py-27. 
I'd like to enforce that, but seemingly I can't, because the invocation 
in make.conf for default version does not enforce it in all situations.

If something wants another version of python, I want it to fail, ideally 
spitting out a usable reason why. Is my position unreasonable? I hope it 
isn't. Maybe it is? I dunno.

thanks,
