I've noticed (and brought this up previously) that pianos with filed bridge pins tend to have looser pins over time in the environment around here than those that are not filed.  (Although this could also be a "pressed-in rather than pounded-in" difference as well.)  Think there is anything to that?

Absolutely!  I know of one manufacturer who has abandoned "filing" the bridge pins for that very reason.   The use of power tools to level the tops of bridge pins and the resulting heat and oscillation certainly results in loose pins, not just over time, but right out of the gate.
