 - AFAICS tools packed with kernel generate but do not consume .pc files
   while JSON and jq are commonly used througout the kernel ecosystem
 - .pc files would be shipped with libkmod development package, not the
   kmod tool in a binary distribution

Other than that JSON and .pc files are roughly quivalent in usability.

Thanks
