The telephone keystone has a foot of service loop coiled up in the box
behind the wall plate.  There's nothing "tugging" on the keystone
from the "inside".

Rather, the force exerted on the jack by the *phone* (not phone CABLE)
being mated to it is enough to dislodge the jack.

The other wall plates, here (typ 3 and 6 unit) don't exhibit the same problem;
but, they are interfacing to discrete *cables*.

I have no idea how a string of 24 keystones in a 16" span would behave.
Given that each connector is 5/8" wide, that only leaves 1" to distribute
between the 24 connectors.  The units that I have are nominally 3/4" wide
(I have several different models from different vendors; some are *really*
wide -- like > 1" -- it appears to be a design decision as they all claim
to have the same performance characteristics.  But, I don't have any that
I could edge-stack at 5/8" wide to achieve the same density of the
stock panels.
