@boy-uber the thing you are suggesting is a pretty big undertaking and
beyond the scope of this PR.
If you are going to add structured plans to the explain output, you
probably also want some guarantees about stability over multiple spark versions
and you probably also want to be able to reconstruct the plan. Neither is easy.
If you want to have this in Spark, then I suggest sending a proposal to the dev
list.
