You already can. You just can’t sell them to other people on Apple’s platform.

To my knowledge you can either side-load na app from Xcode using the free developer account, but the signing certificate will expire in 7 days, or you can pay 100 USD to Apple and use a personal team to be able to side-load apps whose signing certificate is valid for a year. And you are limited to 5 apps only. Is this incorrect? The only reason I care about this legislation is because I want to side-load an app or multiple apps and don't have to worry about making an Apple Developer account or worry about signing certificates at all. In fact, I'd like to be able to build and compile an app on Linux, in CI, download a file and just drop it on my phone and run as an app. No accounts (like Apple Developer), no payments. Is this possible today?

they disappear after a week and i can only have 3, i'd have to pay $99/year to have unlimited apps and sign for a year
