I don't think the idea is that the upgrade will take it from decent to stellar compared to other things you might be able to buy for the same money, it's about paying a bit extra now to be able to go from decent-in-2026 to decent-in-2031 while paying a fraction of the cost that you would buying a full replacement in 2031, not to mention saving a bunch of waste. And then in 2036, and 2041, and 2046... They haven't been around long enough to be confident it'll work out that way, but that's the bet in my mind.
