I think "First Edition Feel" differs from merely "First Edition" specifically in that it avoids a lot of your complaints. That is to say that if someone is playing a game that "feels" like first edition, they are de facto also specifically not playing first edition. Presumably because they like certain esoteric qualities of first edition play but do not like the mechanics.
Maybe... really, what feels like D&D to me, exists in every edition, at least up to 3x, and then to PF (I haven't looked at any WotC products since 3x). For a distinctly 1e feel, the mechanics or lack there of, is the primary cause of that specific "feel". From my perspective, if the mechanics doesn't match 1e, it cannot possibly have the 1e feel, rather the D&D feel, and as stated, that general feel isn't much different in any other edition of D&D. When I first started playing Pathfinder, it distinctly felt no different than any other D&D game, I've ever played. So I disagree its even possible to emulate 1e feel with a different rules set.
