We should change that in core-updates-next, if possible. I think that native-inputs shouldn't end up in the final binary as a reference, especially when cross-compiling (but we don't do cross-compilation much in Guix - usually, we let qemu-arm emulate the ARM CPU on x86_64 and just call the target tool :) ). If there are indeed parts of the same package, one a native part and one a runtime dependency part, I actually write the same package reference twice, once in the inputs, once in the native-inputs, in my custom package definitions. In a "previous life" I did a lot of Linux cellphone development and, there, it was kinda important that a x86_64 toolchain doesn't end up being referenced in an ARM binary, so the habit stuck - and I think it's important to distinguish the mold used to form a product from an integral part of that product.
