Was this change motivated by someone wanting it?

Regardless, I think this would still be incomplete, because you can also use control addresses to send this message. I'd suggest just changing it to an optional from flag, and using that address if set. If unset, I'd probably default to using the worker.

@arajasek added the related ticket. What's a control address? Changes have been made

[arajasek]

@geoff-vball "Control addresses" are a set of addresses that can control a miner. They are significantly less powerful than the owner, and have a similar privilege level to the worker with some key differences:

• you can have a set of control addresses, but only one worker
• they can be either secp or bls (and maybe even, like, multisigs), while the worker must be BLS
• only the worker can sign block headers.

The idea is just to have more than one address that can do things like submit posts, seal sectors, etc...so if one key is inaccessible / out of funds, a fallback control address can Do the Thing.

See the miner actor source code for more.
