Granted I have no engineering background and 2 unrelated college degrees, my experience keeping magazines loaded for extended periods of time is that the springs gave out. My basic load on my vest I kept reloading (because I kept firing it), but the extra "grab mags" in the truck for M4 and M9 just sat in a crate. After about 90 days or so, I decided to empty the magazines and maintain them, (even though our armorer said the same thing, that they would be OK) as this was my responsibility. The majority of the rounds "fell" out of the magazine after the first couple came out, because there was not enough spring tension to push them up. Conversely, the magazines I used regularly, functioned fine throughout that particular deployment. The only magazines I had to replace were the ones that remained loaded for long periods of time and the ones I left on the ground doing combat reloads without the time to pick them back up.
I implemented magazine rotation in my rifle squad on my next deployment also, and weekly magazine inspections (bent lips, broken followers, etc) to make sure all of our gear was functional for when we needed it the most.
Even my older Springfield XD springs (bought in 2007) were worn out from keeping them fully loaded. This is a 10 round compact mag and a 13 rounder, both .45 ACP. I will not be back home until tomorrow from work, but I can disassemble the magazines and take pictures of the ones that I used to keep fully loaded vs the magazines I rotate. The magazines that I have in a rotation are in much better shape. And these are clearly "modern" magazines with "modern springs and steel".
You can feel free to tell me I'm wrong and that engineering says I'm wrong, but my own personal experience tells me otherwise. I will continue to rotate magazines and replace them as necessary. DO NOT TAKE THIS AS ME TELLING EVERYONE WHAT TO DO. I suggest you only do what you feel comfortable doing. If you want to keep them loaded, OK. If you want to rotate them, OK. Do not flame me for making a blanket "you should do this statement", because if you do, I will refer back to this paragraph, because I am not. These are my own personal experiences, at home and at war.
