[FLUX-YOU]

Preferences have become a pretty natural part of using a computer, I'm not sure why we can't rely on users trying that when they run into problems.

I would be worried about endless forking of defaults as a feature of newly built tools, leading to a bunch of new tools that will be harder to maintain.

If they can't manage implicit data casting preferences (if those exist, they may not), surely handing them something more complicated like R, MATLAB, or SQL is even worse.
