This is nothing new. v1 of something is always easy. Now in the coding assistant world, everything is v1. Let the tools go through a few deprecation cycles, weird things being added that don't map to the original intent, floods of overlapping tools and docs and everything else that someone has to reconcile, different LLM technologies that you need to support and adapt to, etc., and then see how things look.

I think all three things you mention come into play, but it's a bit early to judge whether the world has shifted or whether this is mainly a result of everything being fresh and new.
