This would be one option.

I thought about providing a special-case implementation of
udev_enumerate_scan_devices() which fires when there is only a
property match and nothing else. In this case we could just walk
/dev/.udev/db (which we have to do anyway to match the properties) and
skip the /sys walk. This would speedup other applications as well
which search for tagged devices.
