Well, I'm not really sure this was intentional, but I wonder how other bus
types work in that respect?
We have the same for platform bus, if that's what you are asking.

Do we? I don't recall seeing per device modaliases on other platforms on their platform buses.

And actually I don't see that happening in drivers/base/platform.c: platform_uevent() either where just pdev->name is used but not pdev->id (which is used with pdev->name for dev_set_name()).

This makes me thinking that perhaps "pdevinfo.name = dev_name(&adev->dev);" in drivers/acpi/acpi_platform.c: acpi_create_platform_device() should be fixed too as now modalias for ACPI registered platform devices differ from platform devices that are registered in other subsystems (e.g. regulatory, pcspkr, alarmtimer, etc devices)?

I can send a patch for that.
