Review Comment:
```scala
Welcome to Scala 2.13.12 (OpenJDK 64-Bit Server VM, Java 17.0.9).
Type in expressions for evaluation. Or try :help.
scala> classOf[scala.collection.mutable.WrappedArray[_]]
^
warning: type WrappedArray in package mutable is deprecated (since
2.13.0): Use ArraySeq instead of WrappedArray; it can represent both, boxed and
unboxed arrays
val res0: Class[collection.mutable.WrappedArray[_]] = class
scala.collection.mutable.ArraySeq
scala> classOf[scala.collection.mutable.ArraySeq[_]]
val res1: Class[scala.collection.mutable.ArraySeq[_]] = class
scala.collection.mutable.ArraySeq
```
Using the Scala 2.13 shell,
`classOf[scala.collection.mutable.WrappedArray[_]]` and
`classOf[scala.collection.mutable.ArraySeq[_]]` both return `class
scala.collection.mutable.ArraySeq`, indicating that there is no actual
`WrappedArray` type in Scala 2.13, so I think this is not a breaking change
