Turns out, there's already been official errata to fix it. It's not in the online official FAQ and Errata document. Apparently it's in the Player's Guide.
I never bought the Player's Guide. There's a number of reasons for that decision, one of which was that it was a reprint and compilation of a number of products I already had so "why waste the money?" Apparently the answer to that question is "You should 'waste' the money, because along with all the stuff you don't want or need in that reprint book is a handful of critical game-changing rules errata that will never be mentioned in the online FAQ." :( Kinda dumb.
Here's the relevant bits from page 89 of the Player's Guide:
To discourage this behavior and highlight the dangers of combatin your game, players should be mindful of the following generalguideline for healing: each character may benefit from each specificsource of healing once per day. Healing has its limits.For example, a character who is healed by a Shallyan priest’sSoothing Touch blessing cannot benefit from a second SoothingTouch blessing until the following day—though a different blessingsuch as Cure Wounds could still be applied. Likewise, only oneapplication of the Splints & Bandages action, one successful FirstAid check, one healing draught, and one good night’s rest can beapplied toward an individual character’s recovery each day.
