Is there a way to make it a dependency?  Though I suppose that would
still leave the issue with Pharo.  I'm puzzled to hear Pharo doesn't
have it; why doesn't Pharo run into the same problem?

If NewCompiler is a moving target, it might make sense to pull the known
to work with magma into the magma package.

Otherwise, I think the idea of having it off by default with
instructions (and recommendations) about how to turn it on is a good
one.
