The thing is just because a few take the time to do that doesn't mean most developers do and it seems like most don't want to take the time to do so. But, more developers may be interested in using an emulation layer if it's supported and easy for them to use. If developers see their titles being purchased and played more on Linux systems because of this, this gives them more incentive to put more effort into developing native Linux clients and providing proper support.
The way I see it, devs aren't obligated to support any system they don't want to. I really appreciate the ones that take the time to support Linux natively, or even by using an emulation layer because I realize they don't have to. If this makes more developers realize Linux is a viable ecosystem for them to make games for. Even if it's just through an emulation layer to begin with at least they're making some efforts which is more than can be said less than a decade ago.
