Not as useful I think much narrower a sub function of the HS.
Different genre. The HS us nothing special, if you wanted a really gritty game using the 4E engine you could heal a single point if damage overnight.
Adding healing surges counters that goal. Healing surges are a replacement for 3.5 healing via wands and magic.
You're under the assumption that healing like that is a good idea. If you did a WW1 RPG you wouldn't want that type of healing full stop. Lose 30 go and have a condition tracker you might spend the next month or more in hospital.
Sucks in D&D terms but if you're using the engine to make WW1 Trench Warfare the RPG it makes sense.
