It would stifle the specific marketplaces where, when they "open up" to third parties, wish to retain arbitrary special privileges for first party offerings. There's a reasonableness metric there that needs to be evaluated. Nothing is simple. If you're giving in-house apps special privileges because you've implemented some core functionality using mostly generic APIs and just a few special hooks.. that's one thing. If you're giving in-house apps special access to random "nice to have" things, or participation in various contexts (e.g. sales, promotions, etc.).. in order to boost your stuff against others, that's another thing. The details matter.
