   Closing in favor of #6542. Rather than rescale in the dispatcher and keep 
chasing every place Spark reads the value as returned, that PR stops 
dispatching DataSource V2 functions at all, which is what 1.0.0 did. It turns 
the `StaticInvoke`/`Invoke` catch-all from #5692 into an allow list of Spark's 
own classes and checks the whole dispatched tree, so the cases found here 
(transitive parents, projected aliases, `explode`, a dispatched `map(...)`, 
`ApplyFunctionExpression`) all fall back to Spark. @sunchao @parthchandra 
@comphead those cases are now the tests in #6542.
