Comment (by snowleopard):

 Another option would be to provide a setting in `UserSettings` as part of
 the user build flavour, which would be a bit more uniform (all settings in
 one place), but perhaps less convenient for users (since this requires
 recompilation of Hadrian).

 To me, having many different ways of providing settings to Hadrian (CLI,
 `UserSettings`, environment variables, something else?) is confusing, but
 perhaps this is perfectly normal/expected for GHC developers.
