By making the feature an optional, off-by-default loader and nothing more.

I think you're arguing that the feature will be misinterpreted and
misused.  I disagree and can't find a way to agree with you; I still
think it's simple enough that it won't cause the kind of mismatched
expectations that lead to unwanted behavior and bug reports.

While I disagree about the consequences you think it will have, I'm
proposing it before committing code exactly so the maintainers can make
up their mind.  I think we've both stated our case clearly at this point.
