Though I would consider this unlikely.
Prison Architect ran into this. It shows gang violence, drug use and executions, all of which are red flags for those who rate media. Funny story: Prison Architect actually received a notice that it was in violation of the Geneva convention. Papers Please, an indi great, might also have been shunned had Valve/MS adopted MPAA-like content moderation.
This already happening with frameworks like Unity.
As the plethora of capable devices increases, especially in the non-traditional gaming platforms like mobile and VR, the ability to support any device is going to be demanded by developers and will continue to improve.
The line between compiling for native and compiling for an emulation layer will shrink until there isn't really a difference. That's the only way for game developers to be able to keep up with new devices being released every other week.
The other benefit is keeping old catalogues around and playable into the far future, as long as we can keep beating DRM or always online mechanisms!
1) The ease of quality emulation leads to developers ceasing native linux support, resulting in lower quality linux gaming overall.
2) The ease of quality emulation leads more gamers to be willing to migrate to linux as their primary OS, thus helping linux come closer to being a first class deployment target, resulting in higher quality linux gaming overall.
Of course this isn't a dichotomy, but rather I think it's often unwise to look a gift horse in the mouth, especially when you're looking at hypotheticals.
