Right now, each file in Rails core is responsible for loading the
extensions it needs. It has no intention to push that to the caller, but it
does because loading extensions has a global effect.

In the alternative approach with refinements, the (vague) idea would be the
same, each file still loads the extensions it needs, the difference is
precisely that it does not have a global side-effect.

By now we are talking about AS, and as a second iteration, Rails core (and
all this is speculative at this point). We have not talked about Rails
applications, which would still load all extensions unless the bare flag is
true using the compatible behaviour that was outlined before.
