True, but even if Steam were to offer a x% lower cut on sales for Linux users if the developer makes a Linux-native build, it'd still not entice many to build and maintain a native port if they are only saving x% off a tiny y% of users. Other poster's point being that incentives like this would actually become enticing to companies when Linux market share (Proton users) increases.

Doubtful Steam is gonna offer a share cut on all sales when it runs on Proton for the 2% of userbase using Linux, and from that only a minority would care whether or not it's native anyway.

Valve could start by releasing a Steam Deck SDK for Visual Studio that exposes an "Export to Steam Deck" option when targets the latest release of Steam Linux Runtime.

Currently they offer Docker containers which is good but could be improved.

Back when Steam Machines were a thing and Valve tried to only push Linux native games, game developers got placements on Steam Store's landing page banner in return.
