What is it missing that makes you feel it is unrealistic?
It's not an option for which OS to flash onto my DigitalOcean VM. Getting it going on Raspberry Pi is largely undocumented.
For desktop, it doesn't (officially) support many window managers or desktops.
It is hoped that the cloud images project will get Alpine available in all of the main platforms, we've done AWS already starting with 3.13.
I am tempted to go try it on AWS, but I am sticking to DigitalOcean for personal projects for reasons. I will be very happy when it shows up on DO.
I had a laptop for a while that I built up from alpine-extended to a pretty nice side machine, complete with Sway, vim, Rust, Firefox, and a couple others.
