Hi there
I consider buying a Framework Laptop, and what is holding me back is the casual UEFI.
Coreboot offers an open source, faster booting and secure alternative.
System76 and other sources have already ported it to several mainboards.
I suggest this being combined with the upcoming AMD variant, in case you can develop a port.
Other than that, I can also see value in an option to ship with Intel ME disabled by default.
