Why do you think it's missing it? It has the same persistence as the mosh-client on a deskop. That is, the connection will persist as long as the client process exists. If you are observing anything else, that would justify a bug report on Blink. The one complication is that iOS can sometimes kill background processes at will, which would also kill the mosh-connection. As far as I know, the Blink team is currently working on dealing with this better (issue #59). It shouldn't happen very often, though, and I've certainly had Blink persist in the background for multiple days.
