I understand, the simplest case being a SCSI adapter sitting on a PCI bus. Such a driver obviously would need Rust bindings to both subsystems. But it's rare for drivers to "require some modifications even in other subsystems" (quoting the message I replied to). Usually driver changes are fairly self-contained.

It is not the driver requiring changes to the subsystems that gray wolf and broonie are talking about, but the other direction. I.e., a change to the subsystem that requires all users to be adapted. In this case the maintainer of the subsystem has to adapt the rust wrapper for the C API.

Right, and especially drivers needing some new subsystem improvements to cope with some new feature or usage pattern that the hardware has - this is especially true for things not on standardised buses (or not entirely) where it’s much easier for hardware to do new things.
