Kind of. Yes. ;)

But I would still argument that it should be default behavior of 
licensecheck, to not looking for other formats if SPDX is provided.
Checking for SPDX and other formats at the same time/file would 
contradict the goal of SPDX.

If authors using SPDX and extra license information on purpose they are 
using SPDX the wrong way.

So doing it my way would be a more pedagogical and train/force the 
authors to learn how to use SPDX the right way.
