Summary

Currently, the simulate RPC only supports simulating transactions on the current ledger.

A very useful feature would be expanding these capabilities to support:

• Simulating transactions based on previous ledgers
• Simulating transactions based on certain amendments being enabled/disabled (e.g. in a different state than they actually were/are in that ledger)

Motivation

It would make ledger replay much, much easier, and enable much easier analysis of past data/transactions.
