I feel relying on WINE and Proton instead of building a proper GNU/Linux ecosystem will eventually backfire, it didn't happen already because thus far Microsoft chosen to ignore it.
However as Steam vs XBox slowly escalates, Microsoft might eventually change their stance on the matter, forcing devs to rely on APIs not easier to copy, free licenses for handhelds, taking all Microsoft owned studios out of Steam, see which company has bigger budget to spend on lawyers, whatever.
