Good discussion! Since I started using Linux about 15 years ago, I have developed simple bash scripts that removes and installs the things I need - nothing else. Everytime I need to reinstall and setup a new machine I can just reuse them. I understand that this is not for the general user but for me it is perfect. Sane defaults are fine, but I have yet to find one distribution that does MY sane defaults. Solus is close but not perfect in any way.
I have read in earlier discussions that at least some of the Solus devs doesnt like Welcome screens or software. For me though, that would be brilliant. Startup Solus after installation, and BAM: "Welcome to Solus, what can we offer you now? Here is a link to the community. Here is where you can decide Chrome or Firefox, this or that. And, most importantly, here is a button if you just want to skip this whole damn thing and just start using the system using sane defaults."
As for why I dont want for instance Libre Office preinstalled is that I dont use it. Why should I have libraries, prerequisities and stuff installed that can collide with other software I have installed? But as I said, not a big problem, I just remove what I dont need and let others decide.
