How is that different from choosing not to adopt a technology because it’s not widely used therefore not widely documented? It’s the timeless mantra of “use boring tech” that seems to resurface every once in a while. It’s all about the goal: do you want to build a viable product, quickly, or do you want to learn and contribute to a specific tech stack? That’s the trade off most of the time.
It's a lot worse. A high quality project can have great documentation and guides that make it easy to use for a human, but an LLM won't until there's a lot of code and documents out there using it.
And if it's not already popular, that won't happen.
