I think you might be able to get the principals at Elecraft to sign up
to this idea.

Well, it's a known issue.  It goes two ways, too.  I have a neighbor
that runs all gain controls fully clockwise, to the point that he
takes up half of 80m with splatter.  This renders the K3 deaf, because
there is serious on-frequency signal.  If I could just get this guy to
understand that he's supposed to keep his RF energy on frequency, and
could explain that using reasonable gain settings is one way to
accomplish this....  the problem would go away.

No - I've come across the same complaint from others.  The K3 remakes
how the world will use HF radio.  "In between" takes on a whole new
meaning.
