The other way around is problematic as well. A friend of mine had a 2018 15” MacBook and had to get it repaired under warranty because the battery swelled up and made the trackpad stop working correctly. The “Genius” at the Apple store said it was because he always left it plugged in, and that the problem is fairly common. Apple has recently started allowing MacBooks that are plugged in long term to hover at around 90% battery instead of always keeping it topped up presumably for this reason.
