We need a cross-platform React component system at my job, but we're going to only be sharing bits and pieces of the apps, across a pair of large existing codebases with their own design systems and architectures I hate how so many of these things want to be a kitchen-sink framework that owns the world, instead of a library you can adopt piecemeal where it makes sense
