Let me try to summarize the points:
- you think MODULE_AUTHOR without MODULE_MAINTAINER confuses users
- Alan wants MODULE_AUTHOR to stay for easing showing authorship of code
  to people
- I (and others) think MODULE_MAINTAINER wouldn't make sense

Is there any good solution for this?
E.g. modinfo could be changed to no longer defaulting to show the author?
