1) This requires that the .env files are run through CPP, which is
   only added in a later patch.
 
2) Even if I add an "#include board/<vendor>/env/common.env" in my
   <board>.env files, your logic would trigger on the existence of
   the common.env file and ignore the <board>.env files.

Best regards,
