Just use Heroic launcher. Works great.

I believe the problem is that most of the games they host are Windows games, so in that regard, Linux doesn't make sense.

And maintaining something like Proton is pretty complex, there's so many different distros. Actually ensuring the game works probably was too big of a task for them.

You can always add your gog games to Lutris though.

The vast majority of games on Steam are Windows games, yet the Linux Steam client runs them fine via Proton.

I don't think people are asking for GOG to make Linux-native games. People are asking for an official GOG client that can handle installing games via Proton/Wine, handles cloud saves, account management, etc.

If a bunch of open source hobbyists can create a viable multi-platform client (see Heroic Games Launcher), then so can GOG.

Proton runs GOG Galaxy well too, so what exactly do you want?

I would want Galaxy to run things in Proton, not Galaxy to run in Proton.

I use https://lutris.net for this. One starter for all.
