Hi Robin,
No, I consider it a minimal necessity to renotch and replace 
bridge pins (bedded in epoxy or CA) as a matter of course when 
restringing. Even if the bridge looks fine, yank one of those 
old pins out and take a look at it. It'll have a notch in it 
about the height of the string where the shrinking and 
swelling (seasonal changes) bridge cap has slid the string up 
and down the pin through the years, scrubbing a flat spot. The 
same process also crushed the notch edge and loosened the pin 
in the cap, producing the usual false beating trebles. 
Cleaning up the bridge cap and notches, and epoxying in new 
pins throughout makes a much nicer and cleaner sounding job, 
without the false beating treble.
