I recently started using Aider and had that thought about too many commits. What I realized though was: (1) if I'm going to contribute to a project, I should be working in a local branch and interactively rebasing to clean up my history anyway (and of course carefully reviewing Aider's work first) and (2) if I'm working on my own thing WITHOUT LLM, I tend to prefer to commit every dang little change anyway, I just don't remember to do it because I'm in the zone and then inevitably wish I had at some point.
