Yes, and that's great. Ideally you would want to be able to enroll your own security keys like Secure Boot, but I take all I can get. Android is not equivalent to Pixel though. Not even all Pixels do it by the way (notable exception was the ones sold by Verizon). So do macOS T2, and chromeOS developer mode (potentially with physical hardware screws to deter unintended misleading of a layperson).

However, all of that is pretty much orthogonal to what Epic wants, which is my point. Epic does not care about user freedom in that sense, just haggling to get a cut from 30/15% to ~5-10% and they'll be on their way. It's just spun as a user freedom thing (which is actually a valid request, but accomplished with very different means).
