> They explicitly explain your workflow needs to change

How about - don't break my workflow unless the change is meaningful?

While we're at it, either make y in x.y mean "groundbreaking", or "essentially same, but slightly better under some conditions". The former justifies workflow adjustments, the latter doesn't.

I have used nothing but Sonnet and composer for a year and they work fine. LLMs were certainly not unusable before and Opus is certainly not necessary, especially considering the cost. People get excited by new records on benchmarks but for most day to day work the existing models are sufficient and far more efficient.
