See, I don't this the OSR knows what it is. Or, more correctly, there are SEVERAL OSRs going on under the banner. You do have the hardcore-mode "We die and we like it" going on, but you also have the "rulings not rules" crew, and several more besides. (Individual groups know what they're doing, but some think other "OSR" groups are also doing the same thing they are - and they're not).
So, when we attempt to describe the OSR, we typically only describe one part of it.
I do think you can find examples where the new designers are including bits of "hard mode" when they meant to be doing "light rules" because they conflate them together
