[Discussion] Policy Decision on BlockedAddrs in SDK v0.50 bump

[dongsam]

Context:

• Currently upgrading to SDK v0.50 https://github.com/b-harvest/Canto/pull/53
• Discrepancies found in BlockedAddrs between v0.50 simapp and Canto's implementation during upgrade.

Differences and Suggestions:

1. Gov Module Account:
   • v0.50 simapp allows token receiving in gov module account, not blocked in BlockedAddrs, unlike Canto.
   • This change was due to a https://github.com/cosmos/cosmos-sdk/pull/12852 aiming to handle CommunityPool -> IBC transfer via gov module account.
   • Suggestion: If no similar case is planned in Canto, keeping gov module in BlockedAddrs might minimize potential risks.
2. Distribution Module Account:
   • v0.50 simapp disallows token receiving in distribution module account, but Canto currently allows it.
   • This was an exception from Canto's initial setup, with unclear intent.
   • Suggestion: Blocking the distribution module account in BlockedAddrs to minimize risks unless there's an unidentified reason to allow it.
