There have been plenty of other color schemes that I think it's safe to say have been inspired by Solarized and this is very satisfying to see. Many of them have done a better job at thinking through the git structure of their projects :)
As my eyes age I often use Solarized in higher contrast configuration, so I'm sensitive to this issue.
1) I don't use Solarized everywhere religiously. I use it a LOT, no surprise. Still my preferred color scheme in most editing, terminal, code situations. But I am happy to use other well designed colorschemes in various contexts (writing, task management apps, etc.). Even when Solarized is available, sometimes variety is what's called for.
2) Solarized was designed to enable the colors to be used in high contrast modes as well. As my eyes age I sometimes will apply the colorscheme in a higher contrast mode. This adaptability is sometimes overlooked but it is inherent and intentional to the design.
Perhaps so. I've attempted to find some other color scheme. The most significant color scheme change I was able to stomach during the last ten years was from Solarized Dark to Solarized Light. Thank you <3
