Yeah, im not a big fun of GitHub (especially after Microsoft aquasition), but I also hate that stupid 'we need to grow', 'we need to expand' attitude. Sometimes, tool is done and there is really not much you can improve upon. Especially from UI stand point of view. If you start to force that improvement, usually you end up with over-engineered stuff that starts to be pain to use.

Not always legacy stuff means it bad or should be avoided. Actually, most of the time its kinda other way around. It means its stable and just helps you get the job done. The balance between legacy and progress is not that obvious imo.
