Offloading compilation for these single-source languages pretty much just combines one "host" compilation job with N "Device" compilation jobs. Doing `--offload-device-only` and `--offload-host-only` simply does one part of that. There's probably some flags that behave differently depending on which end you're compiling on, so maybe it would be useful for separating that behavior if needed.
