Resource Estimation & Balancing Issues

A key problem for developers is about getting accurate and reliable execution units for a transaction. Some known issues:
- Balancing and Resource Estimation is somewhat mutually recursive. Balancing can increase the UTXOs, which increases any iterations over the utxos, resulting in greater resource usage, resulting in more fees, etc.
- signatures need to be applied so that any looping over the witness set is also consistent, the signatures are then invalidated when the transaction is balanced, necessitating re-applications of cryptographic signatures as well.

it would be great if this process could be simplified.
