Comma should be on the vendor device ID line, so if VENDOR_DEVICE_ID is not defined, then the INF section is still valid, although it 'promotes' 0002 to HWID from CompatID

The main potential issue here is determining if Microsoft / Windows Update will allow an update distribution to the vendor device ID without distributing for the compatible IDs, so drivers will only install via Windows Update on the vendor device, not on others - if this is not possible, then an alternate method is needed. I've so far not been able to confirm this either way, but it would appear that driver distributions are enabled for a specific HWID.
