As a previous poster posted, you are in a non-radar environment when
you hear "radar contact lost". You are also in a non-radar environment
when you see mandatory reporting points. I believe that this mostly
applies to the great wide West.

When flying at, or near MEA in the great wide West there are lots of radar holes where ATC doesn't bother to terminate
radar because you will reappear in 10 or 15 minutes. So, they say nothing.

As to the remainder of your concern TCAS has gone a long ways to solving the en route problem of midair potential for
airliners and biz jets. That is the real solution for everyone. It should be a higher priority for light aircraft.
