Theory-first analysis: Bespoke package manager, NIH symptoms. Might work great. IDK. Another interesting data point to watch, given how Xorg features in its Technologies list (
https://getsol.us/solus/technologies/ ). Interesting dependency-focused build system. Solbuild seems neat. They write a lot of code in Go. Budgie is written in Vala, the weird GTKObject-based language.
Seems a sensible choice for someone who likes Mint, but rough edges will be weird to solve because it's not "like" most other distroes. No idea how readily you'll find them. Project gives a very polished, consistent vibe, devs seem like they're not resting on their laurels.
