Description

The node won't be punished which keep sending malformed data through P2P.

I agree that it's better to have the P2P port protection.

Potential solution: whitelist rule

In reality, there are fewer cases where one would actively want to run a sync-node of an app-chain, which are usually maintained by several trusted validators.

If an app-chain is not completely permissionless, then open p2p port with a whitelist rule is accessible IMO.

So I suggest to postpone this optimization plan. Would like to hear @driftluo 's opinion.
