I think that you will find that many are put off from immersion silver because: 1) they don't have the background to differentiate between the modern immersion silver and the old electroplated silver that electromigrated at the drop of a hat. 2) both Underwriter Labs and Bellcore had long time positions of "thou shalt not silver". Most are not willing to spend the money to pursuade Bellcore and UL that their position is antiquated.
