I haven't seen anything on the board where someone has stated that they have removed them. The potential for significant deterioration of the boots, in particular on the back plugs where the temperatures are higher is certainly there. It is a PITA to get the boots off. in particular if silicone grease wasnt used on those boots. The first time I changed mine after I bought the car, I had a heck of a time getting the back ones off. I lubed the new wires up well with the dielectric grease, and they're much easier to take off.
