This was formally proven a few years ago! The set of states achievable under thermodynamic transformation follows a partial-order relation called “thermomajorisation”. This is a beautiful result that illustrates your point.

Started reading “the physics of filter coffee” by @jgagneastrocoffee.bsky.social —highly recommend! While browsing around, I found out he also developed an app to measure grind size distribution. Super useful—I’ve always found it hard to get clear grind size advice or compare grinders properly.
