The idea is some people view hp as meat and others don't. The question is how can fifth edition allow both playstyles to exist in the same game but at different tables?
I don't know if it's possible.
"Hp as meat" is really simple and intuitive, and works best for beginners. A hit causes a wound, everybody understands that.
The real limit of "hp as meat" is that it doesn't match D&D typical healing rules, spells notwithstanding, since "it's magic" always works as an explanation. But everything else, including natural healing rates when sleeping, healing through mundane skills, short rests etc. don't work well with "hp as meat", simply because they are too fast (in order to allow the PC to keep going without resting for weeks each time), and the result is challenging suspension of disbelief. But is it really a problem of "hp as meat" or is it instead a problem of D&D typically fast automatic regain of HP?
"Hp as whatever" is trickier to explain (and the fact that every time we discuss something related to it, we get a 10+ pages thread of arguments, is a clear sign that the whole idea is not as natural and spontaneous as the first one), and you always stumble upon cases where your suspension of disbelief is seriously challenged as well.
But a RPG can certainly work with either idea as a core assumption. The problem is whatever choice, the rest of the rules should probably better support that chosen assumption as much as possible, to help players keep their suspension of disbelief.
A half-meat/half-fish situation isn't really that good IMHO. Perhaps the best that could be done is start with "hp as meat", and confine all "hp as whatever" rules to optional character material that can be easily ignored (e.g. that "damage on a miss", which exists on an individual PC's basis and is not a general rule). The other way around doesn't work however, because if "hp as whatever" is the starting point, it's quite impossible to put the genie back in the bottle for those who want the other approach.
