Does catch already cover this edge case?

Explain response format is always JSON?

Using format is not particularly appropriate, mainly because I want to avoid adding an extra parameter.
_ppl/_explain?format=simple
Do you think should we add a new parameter for it?

Not sure if I understand this right. In Calcite, explain format is actually referring to JSON, XML, DOT? Ref: https://calcite.apache.org/docs/reference.html. If so, I feel making different explain content as different response format is a little confusing.

@dai-chen You are refering to Calcite SQL? IMO, it is out of scope of this PR.
@LantaoJin We should consider to add explain command in PPL in future.

I'm thinking shall we fit all these into existing ExplainResponseNode structure?

How about add a ExplainResponseNodeV2? The new explain response is plain but ExplainResponseNode is nested.
