Crowdfunded games are more commonly released for Linux than publisher funded games, and they more often represent not the mass market, but something interesting that creators want to pursue. So for me it translates into better games on average on Linux. But as you said, it's subjective.

The market however is viable for everybody, but as I said, if everybody from the Windows gaming market will start releasing games for Linux now, it can actually hurt it, rather than improve it. Gradual growth is better, and it's already happening. Tools wise, the situation is getting much better as well, with all major engines gaining Vulkan support. Common middleware like Umbra 3D also often supports Linux these days.
