I realize some or many of the shields are fro heat dissipation, but aren't
some for the prevention of stray RF? Just curious..

"In many cases, these inserts were
retro-fitted to shields that were not necessarily made for them -- i.e.
no crimp stop near the top of the shield to keep the insert from riding
up too high when the shield is installed."
Exactly the case with the ones tested, the tube shields tested were
retrofitted with the "accordion" type (better description than waveform)
beryllium inserts.
