I would love this feature too. Besides indicating lost message, it is helpful to show, a trigger from an external system that is not modeled. Or similarly a message to some external actor. (Or it could be response message for the request from the external system)
Proposal
I want to put Endpoints in sequence diagram in some cases.

Example
If there's no recipient after the arrow or sender before the arrow, it will be a line to/from the endpoint.
