I agree with you for almost all of this, just a small nitpick: GC isn't really incompatible with games, for the overwhelming majority of games, it's basically a non-factor in performance if you spend even the slightest amount of time on performance. It's kind of similar to native code - don't allocate too much, reuse resources, don't leak them uncontrollably. It's only a problem when you need guarantees (i.e. the game should never drop a frame) but basically no game fulfills that nowadays and it isn't a player expectation.
