Yeah just like sys.setdefaultencoding, look at how well that worked out.
simplejson has a number of options that you can pass to loads and
dumps, but if you don't explicitly use any of them it does what most
people want by default. I don't see a "loose=True" being much worse, I
probably wouldn't allow people to pick and choose exactly which
garbage to allow (except for the spec ambiguities that it already
gives you control over).
