Is there a reason why minting a key for account is in the account subcommand, but burning is in an entirely new one?

[nxsaken]

I simply went with the formats described in the respective issues. They probably should be under the same subcommand, but I wanted to get feedback first.

[s8sato]

I believe this work will be reverted by the 1st PR for #2085 in progress, which makes an account have a single public key in its ID

[nxsaken]

Does this mean the issues this PR addresses are obsolete?

[s8sato]

Yes. This is an unfortunate conflict, but after opening the PR I will check if the open issues are still valid
