So I haven't felt the need to go with a tiling compositors. I already use multiple munitors, and kind of have designated spots for the apps I use.
I love stability and don't want any surprises after Windows made enough surprises. So decided to go with Debian Trixie, and KDE.
But I use Arch in my spare laptop, btw. EndeavorOS where I experiment some stuff. Maybe down the line I will give hyprland a try on my spare first.
I think it is just chain of trust. Many used Microslop as the trust authority (may be due to convenience? I have no idea). Debian has a nice page on Secure boot and how it works.
