Can the verification of denom be rolled back?

Hi

As an early user of cosmos-sdk, cosmos-sdk supports custom denom format verification rules. Please refer to https://github.com/cosmos/cosmos-sdk/blob/main/types/coin.go#L858. Just as cosmos-sdk supports custom address prefixes, I don't think it should be mandatory to verify the length of denom. This will reduce the compatibility of many products open to the cosmos ecosystem. This is not in line with cosmos's long-standing philosophy of openness and inclusiveness.
