Resource Estimation & Balancing Issues

[Benjmhart]

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.

after some discussions last week there are likely unique balancing algorithms necessary with different types of dApps to prevent utxo fragmentation within the wallet.

recommendations currently is to allow Balancing to be 'pluggable' to some extent, so that dapps can implement the right balancing algorithm to prevent fragmentation while using their specific app.
