That happened 20 years ago now.I don't disagree, it's just noteworthy because all the other variant rules surrounding rest &recovery tend to be so bad
It's the shift from vancian(sp?) prepared each slot to prepared use any unused slot. Back then the cleric would prepare x cure light wounds Y cure moderate wounds etc in addition to the cool spells they want to use doing more than puttin magic bandaids on the party while now everyone who can & does prepare cure wounds has every unused spellslot available for either cure wounds or a spell that lets them do something cool without the old worry about preparing too many cure spells that will go unused & not enough do cool things spells so there is no need to do anything more than charge in & just recover everything before reaching a point where you might feel tight on spell slots.
The consequence of this has been the cleric has moved from it's traditional role into basically another wizard, rather then a secondary Fighter that offered support and healing.
It did mean in AD&D that you might need to retreat and spend an extra day or two preparing healing spells and them casting before going back into danger but that's little different in effect then changing the length of the long rest in 5e.
The difference is the lack of things in 5E that bypass hit points altogether.
