A far better approach is being precise with your prompts and if you find a new model has any bad habits, address it specifically in your AGENTS.md and go on your way. If you want to throw in slop promts, go ahead and add a massive AGENTS.md your employer gave you.

People waste too much time on this stuff. The next version could totally change how the model processes your agents.md.

Get good at promting, use agents.md as a minimal model annoyance fixer, and reset it often (every major release)
