Your first paragraph highlights the issue perfectly. You mentioned Bulma—how many developers have even heard of it, let alone use it regularly? It’s even worse when one app uses Bulma because someone wanted to try it out, another uses Tailwind because it came along a year later, and then there’s a 10-year-old PHP project still stuck on Bootstrap 3.

With something like MUI, everything is where I expect it to be. That consistency lets me focus on learning the business logic, addressing critical bugs, and thus making meaningful contributions.
