Even aside from the good point Gigachad also made, it's not really under Apple's control to make web and app developers be more efficient. People just develop and scope for the power envelope the hardware can provide. It would be great if they optimized for cutting bloat, but they just don't and there's nobody with the ability to dictate that they do.

App review processes are already opaque and inconsistent enough with fairly straightforward rules around what is and isn't around. I don't think devs are going to like it if Apple starts getting opinionated about how you're doing indexing on your SQL.
