The complaint about power usage in suspend is especially sad because it’s pretty much a common problem for Linux on laptops. Not sure if that’s what applies here, but the numbers about match what I see with my Framework. Basically: if you want to use secure boot you usually also want kernel lockdown mode, and you cannot hibernate a lockdowned kernel. At least not without out-of-tree patches. IMHO that’s a giant issue…
While I don't deny that suspend is an issue on Linux I've just never seen this as a major problem? I simply turn off my laptop and turn it on when I need it - boot times are less than a minute so it really isn't a issue for me, just flick the power switch, wait for a bit then I'm good to go.
You might be okay with it, but I suspect most consumers today won’t be.
