Think about VotingRules for grandpa

[dmitrylavrenov]

At the current moment we use default voting rules for grandpa. But there is a way to define a custom rules options like doing finalisation in every 50 blocks, etc.

Here is an example from polkadot node.

Relevant:

• Bump substrate to polkadot-v0.9.38 #584
• humanode-network/substrate@da3a34f
• humanode-network/substrate@15e218a
• Fix longest chain finalization target lookup paritytech/substrate#13289

Closing this, as we have had a discussion about this during the incident. The verdict, in short, is voting rules are fine as is - with 2 blocks delay after best block.
