my 2 cents, I don't think this post will age well. The team I am on is currently swinging back towards more traditional agile after going too lax on planning, retro, estimation, etc for a while. These "rituals" are effective ways to ensure a good base level of inefficiency. If you're feeling like the agile rituals are becoming a waste of time, I would try out doing longer sprints before dropping them entirely. Cutting process relies on good habits from the developers/whoever on the team, and habits can degrade over time. Devs can cut corners without formal process, because creating meetings and facilitating process that doesn't formally exist can feel like just another burden/task switch they have to take on.
