I think maybe I wasn't clear. I have seen short rest REDUCE the incidence of 5mwd. I cannot speak for others, of course, but that's my observation.
Short rest characters can spend all their resources over a short time period, but, the amount they have is small, but regenerates quickly. If you have short-rest characters, you plan to take engagements in stages, not all at once.
And over here I get endless questions from young DMs about whether or not it is normal that players tries to get only "one" fight between long rests. The days of the 5mwd are not over.
Now your experience is great. If you had nothing to do as a DM to reduce the 5mwd but have short rest, great. But that is hardly the case for everyone. When I talk of "enforcing" the 6-8 encounters per day I get angry stares and the: "It breaks the narrative!". To which I respond, which one does, the 5mwd or the 6-8 encounters?
The other solution is to go full gritty with short rest = a day and long rest = a week. And what do I get? the infamous: "It breaks the narrative!" again. Then, some come and watch my live games at our hobby store and see that I do allow the 5mwd when it does not break the narrative but I enforce the 6-8 encounter per day when the 5mwd is just "breaking" the narrative. It is mainly a matter of pacing and I strongly regret that the DMG does not address this. It should've talk a lot more about pacing and how short rest and long rest classes should interact. Instead, we got a few pages worth of world building and other stuff that can be easily found on the internet, that could have been addressed in a setting box set (or book).
And to make it clear, I really really like 5ed. But some decisions and emphasis were not really made with young DMs in mind.
