the above is a good point actually. I forgot to mention: springs are a serviceable item for good reason. They are expected to wear, and to be replaced. That holds true for mag springs, striker pin springs, hammer springs, slide springs, trigger springs, etc.
Guide Rod springs, for instance, are recommended to be replaced every 5,000 rounds, in my experience.
Well, from a long history of working with the manufacture and use of springs I can say that there is no simple answer.

Since we can't know how the springs we get in the magazines we buy are made, it is prudent to exercise caution.
Personally, I would not leave all the magazines loaded. If you have enough magazines, rotate the ones you keep fully loaded and load them all only when you are on business that requires that they all be loaded.
If you must keep all your magazines fully loaded, periodically replace the magazine springs with those of known manufacture, do not buy "bargain" springs.
Springs take a set, that is why with some new magazines it is difficult to get the last few rounds in and as time goes by those last few rounds are much easier to load, which also means when you fire you last few shots from that magazine there is less pressure pushing the rounds up to where they can be chambered. More than one failure to feed problem has been trace to weak magazine springs.
Even the best spring manufactures would probably not recommend that you keep your magazines loaded, but you are, of course, free to do as you please.
True, Wolff sells springs, but if you're implying they're trying to sell more springs, why would they give a tip on extending spring life?

Some just can't apply what they know about the leaf springs in their truck to the springs in their pistol magazines.
