Having http as an alternative to tftp is a nice win. The range of things that can run an http server is much bigger than tftp
>Additionally, adding the TLS layer brings back the missing integrity and confidentiality guarantees and thus paves the way to move critical boot components out of the trusted network, possibly even to a remote location/Cloud.
Doesn't secure boot already provide this or am I misunderstanding something? I suppose secure boot only provides integrity but not confidentiality although I'm not sure how much confidentiality matters given we're just talking about the kernel here

To what extent is this possible for actual metal hardware? I'm sure lots of us are running PXE/TFTP systems and HTTP would be a heck of a lot simpler.
