Additionally, on frequency I have heard holding instructions go out to
every aircraft (air carriers and GA alike) approaching the big three NY
airports when a line of t-storms was about to move through.

The point being that the more you fly IFR, the more likely you will
encounter a request to hold.


Airliners sometimes hold for an hour, or more on STARS serving JFK, EWR,
and LGA. Holding west of Boston is very common, too.
