True.

With the minimal changes to (guix build-system cargo) below, one can use
either the current style or pass “development inputs” as ‘native-inputs’
and other dependencies as ‘inputs’.  Source transitivity is preserved
but you can write packages the normal way.

I modified some of the dependencies of librsvg to use
native-inputs/inputs and you can see when applying this part of the
patch that the librsvg derivation is unchanged.  Good thing is that
‘guix graph’ and ‘guix refresh -l’ work for these packages.

Is this a direction we want to take?

If so, we can have ‘guix style’ automate transformations.

Thanks,
