It seems the Stellar Foundation also have a very “open to humans” philosophy.
The idea would be to be able to send and receive lumens between peers.
But just an idea, absolutely neither necessary nor urgent.
I had a similar idea, except it would be a generic wallet with the means to send an arbitrary crypto to another Jami user. I think this would boost Jami adoption as it gives a greater incentive to join if someone is proposing to someone to be in receipt of a money thereby.
