Similar jacks are used all over the ARP 2600 (42A 1/8") and they work just
fine.  There were reliability problems with some pcb mounted enclosed versions
that had plastic housings.  I believe soldering could deform the plastic
during assembly.  At some point they switched to all panel mounted jacks
with open-frames.

Switching jacks are also used on insert jacks on all types of equipment
(mixers, effects, etc).
