Review comment:
Quoting the sentence in the doc:
> Although scala.Symbol is useful for migration, beware that it is
deprecated and that it will be removed from the scala-library. You are
recommended, as a second step, to replace them with plain string literals "xwy"
or a dedicated class.
unless the sentence is incorrect I would consider it as targeted as future
removal.
