Probably not. If I were a shop, I wouldn't take apart bindings if only for liability reasons, and the bindings that I personally have broken down and rebuilt were all pretty clean inside... the only dirty grease was in the tracks, not the release mechanisms. For my own equipment, I keep it out of road salt and make sure not to store it wet, but for the most part just spray a little silicon (dry) lube in and around moving parts at the beginning and end of a season.
I mentioned the grease because that's about the only thing left that I can think of based on ssh's description.
I'll admit I haven't ever done any work examining the durability or longevity of bindings (my work was focused purely on release characteristics under dynamic skiing conditions, so we only used fully functional bindings)... but based on mechanical principals and material properties the springs shouldn't be anything to worry about unless manufacturers are using defective (as in incorrect temper) parts.
