 However, you should make sure that the source-formatting tools you use do not rewrite import statements in ways that conflict with `OrganizeImports`.

 CAUTION: In general, order-sensitive imports are fragile, and can easily be broken by either human collaborators or tools (e.g., the IntelliJ IDEA Scala import optimizer does not handle this case correctly). They should be eliminated whenever possible.

 As mentioned in <<remove-unused-warning, a previous section>>, the `removeUnused` option doesn't play perfectly with the `expandRelative` option. Setting `expandRelative` to `true` might introduce new unused imports (see <<expandRelative, `expandRelative`>>). These newly introduced unused imports cannot be removed by setting `removeUnused` to `true`. This is because unused imports are identified using Scala compilation diagnostics information, and the compilation phase happens before Scalafix rules get applied.
