To be fair, you probably don't want a native version anyways. Most native games i've played just required me to switch to proton because they had their own share of issues that the proton versions didn't have.

At this point it's better for devs to make proton support a goal(i.e steam deck compatibility) rather than native linux builds. Linux just has too much diversity for native linux support to not be a massive pain in the ass in my opinion.
