fluctuating shield connection will cause fluctuating impedance in the
cable, which will in turn cause anomalies in the signal transfer.

I think exposure's the main issue.  I do see signal problems when I move
my cables using "cheap push-on" connectors even when the connection
feels solid.  Every now and again I see it when I move a threaded
connection, and I then find out that threaded connected is not even
hand-tight.  They do seem to loosen up over time, especially the ones
too awkward to really tighten well.
