Well, if we're speaking in terms of ease of updates - you're right, now they're better than before, although this may be very different across different manufcaturers, for example with this DELL i got lucky and just need to either do fwupd or loading FAT32 flash with bios.exe on it...
But if we're speaking from ease of use and hassle-free standpoint...call me old-school, but i'd rather FreeDOS myself to death, than deal with all those restrictions and not being able to use just plain old OS agnostic non-secure-boot BIOS
On newest hardware, especially laptops like this DELL there are quite a lot of problems with it:
It's not even an option to go usual BIOS route, given "internal SSDs / hard-drives can't use legacy"
Linux's journalctl -p3 -xb will scream like 100 ACPI errors on each boot, regardless of acpi_* grub options, and nobody in DELL naturally would give a crap about it
I've read that there will be stuff like hardware parts serial number / model locks (thx god not for my particular model) for some models in near future...Kinda like Apple crap, where if something goes wrong you can use only specific model of any part without going to their certified support centers and paying extra briefcase of cash
So yeah...Brave new world
I just don't like idea of something very simple that should always work and do one thing right, becoming inherently more complex and therefore buggy
