alt Hacker News> you can just use the heavier one for everything
Because people don't like using heavyweight solutions needlessly. That's the logic that begat C++ and Ada and Multics and ASN.1 and CORBA. All of which were good solutions useful for "everything" in their domain. But people hate them, mostly.
Historically big "everything" solutuions end up losing in the market to lighter weight paradigms with more agility and flexibility. Almost every time. React[1] was such a solution once!
[1] Which really is a shorthand for "modern node-based web development with tens of thousands of npm dependencies and thirteen separately-documented API and deployment environemnts to learn".
The thing is most of us have jobs where we can't unilaterally switch to the 'cooler' solution, and I value my own context-switching overhead much more than I value a slightly smaller bundle or dep tree. I'll much sooner optimize the former than the latter and so the general purpose solution that will solve both my own projects and the work ones typically wins.
