It depends on who you’re referring to as a casual user. My mother for example would certainly have a hard time with it, then figuring out the key to bring up the boot menu (and being faced with a scary dialog that they’ve never seen), then selecting the right device, then likely being faced with GRUB which would also look scary to her, and by then she’d be overwhelmed before even getting to the install portion.
Oh wow, I didn’t expect another release so quickly! Props to the COSMIC team! I can’t recall where the roadmap for the features and their targeted releases went, but I hope we can get Night Light/Blue Light filtering soon.
I also did not know they had a Mastodon account, thanks for the shout so that I could give 'em a follow.
