Please add this to your general topics:
Basic-Auth behavior: As of v3.1.x if basic-auth is disabled on a Grin-Node it still accepts request with a basic-auth password. Is this behavior to be changed in the near future ?

Looks like NSKR/NRD locks are going to require "allow duplicate outputs" to be useful in any practical way.

We should discuss "allow duplicate outputs" as this would be a change to the consensus rules in itself. It may make sense to target this for 4.0.0 as a discrete change (vs. "relative kernels").

The rule is currently "we do not allow duplicate output commitments in the UTXO set".
Allowing duplicates would introduce various edge cases around precedence rules (plain vs. coinbase vs. immature coinbase).
We would also need to consider an adversarial scenario with millions of duplicates etc.

Is this something we want to consider?
Or do we want to continue to enforce uniqueness and work around that?
