I am also asking "What about the future?". Library work provides evidence of need and an example of progress. But every solution has trade-offs. Adopting a library solution is easy: it will have champions and evidence. Somehow we need to go around the loop (quickly) to find evidence of the downsides and more input to finding improvements. I think today ES has a lot of good contributors that can help. So a concrete suggestions: modify your stance on "library first" to ask for evidence of revision. Perhaps we can create a world where Master student projects build the pro/con cases for these smaller but critical language features. Make the goal less "standardize libraries" and more "learn/revise/retry from libraries".
