Prior to proposing such an invasive change which is highly likely to
come up against heavy opposition, why don't you try to work _with_ the
current ruling and the Maintainers to see what others have done to
solve the problem.  I highly doubt you are the first/only developer who
has had this issue.

Do:
  `git grep "\-hwmon"`

... and have a good look around for an accepted solution.
