Reference Design: PE4259 discharge resistors

The reference designs for the SX126x family have PE4259 RF switches to isolate the RX and TX ports. These switches have capacitors directly on their outputs.

In a situation with capacitors on the switch outputs, Peregrin Semi recommends a discharge resistor to minimise stress to the switch ( Is there a reason that Semtech do not recommend this?

(I ask because I am seeing a very high failure rate of these switches in my design, and am trying to figure out why)
