Right, sorry, I must've been tired when I read this. In my mind, I read 
it as "disallow-picked-versions = false". :)

Surely, using the extension isn't an issue. It's just referenced by name 
and installed. That's like saying you can't use gcc (which I assume is 
GPL licensed) to build C extensions.

Right. One is not an alternative to another. But it's useful to know 
what got picked, if you allow things to get picked, and it can be hard 
to pin everything always. Sometimes, you want to get newer versions 
precisely so that you can test new things without having to know that a 
new release is available and update your pins.

Anyway, different issue.
