You were arguing that terrible things would happen if someone
accidentally relabeled GPL code, and specifically that the viral
aspects of the GPL would damage the utility of the site. That's
different from saying that having only one license would make things

Countervailing that is the Python Cookbook, which used to default to
the Python license and moved to an explicit, enumerated set of
licenses accompanied by a strong recommendation for the MIT license.

I think this approach is the best one. Excluding GPL snippets doesn't
buy us much more simplicity in practice and tends to exclude
contributions from the mostly-GPL Sage community and others.
