We’ve started work on this item. We’ve changed the plan of attack slightly:
We will be building out the ability to create API sending keys at the domain level, which will ONLY allow SENDING messages from that domain via the /messages or /messages.mime endpoint.

I also need this as I am providing service to a client, and I don't feel comfortable that the client has free access to my API key in the mailgun wordpress plugin. That's not a very secure approach.
