Querying delegations for a validator at a specific height

Question

Is it possible to query:

the set of delegators for a given validator at a specific height?
the amount each delegator has delegated to a given validator at a specific height?

Something like the output of the /staking/delegators/{delegatorAddr}/delegations RPC endpoint, but at a specific height.

I think it might be possible via /abci_query, but not sure on the path and data arguments.

sounds like you want /staking/validators/{validatorAddr}/delegations, no?

to get a specific height, add a query param ?height=39000
