Is it possible to get the block proposer of current block even while handling a message ?

Motivation
If application can get block proposer of current block while handling a message, then we can design some reward mechanism to block proposer in application.

I would use "mandatory operations" for this use case.

In other cases, message senders can also tip the chain (in the same message bundle).

For native token, yes. I'm not very clear that for application token if we can do that like native token.

I may need to do more survey, 😄
