Coupled with the fact that players have had 10 YEARS to find and come up with an alternative to short rests and playtest their ideas completely and fully to finally get a method they would prefer to use and install into their own games. Goodness knows posters here had invented dozens of short rest alternatives over the past decade that any single person could have yoinked for their own game if they really wanted.
But if no one ever did that and instead just kept using the standard rules (all the while just complaining and complaining and complaining about it) for these full 10 years, never bothering to even attempt an alternative (or convince their DM to try an alternative for even a short campaign)... I have little to no sympathy for them.
There are certainly different models than short and long rests for recovery that may work better for most people. But long and short rests are easy to explain and use. But a different approach would require a lot of balancing and would be a very clean break in the system, not just an update.
So I use short rest is overnight, long rest is several days up to a week depending on circumstances. It works for me.
