import OptJsonWriter.OptOut._
And you'll get the implicit lift, but not the implicit fallback.
You get an ambiguous compile error like this:
[error] /d/sbt-util/internal/util-collection/src/main/scala/sbt/util/OptJsonWriter.scala:28: ambiguous implicit values:
[error] both method conflictingFallback1 in trait OptOut0 of type [A]=> sbt.util.NoJsonWriter[A]
[error] and method conflictingFallback2 in trait OptOut0 of type [A]=> sbt.util.NoJsonWriter[A]
[error] match expected type sbt.util.OptJsonWriter[Foo]
[error] val x = implicitly[OptJsonWriter[Foo]]
[error] ^
