IMO, there is some advantage to over-specing tires. If you do the math, you might come up with a certain load range as an "adequate" tire. However, if you look at the money and peace of mind, the increase in cost to get the next level load range is often worth it. I like to be well within the capacities of my tires without having to bust out a calculator. In my eyes, the tires will run cooler, have less sidewall flex under load and thus last longer with better performance.
In my case, a LR D tire will technically work within specifications (just enough IRC). When I replaced them, LR E tires were readily available in my size at about a $5 delta per tire, so I threw in the extra $20 to get the LR E tires. I feel much more confident about my tires now because I know they're not being "tested".
There is also speed to consider. Some manufacturers will allow for 75mph if the tire is filled to 10 PSI above the pressure for the rated maximum load. While I don't make it a habit to go that fast, it has happened, and I know my tires can handle it.
All that being said, I'm not sure there would be a benefit of putting LR E tires where LR C were spec'd. Perhaps just one level of increase is sufficient? Like from C to D, or D to E?
