I am just a bit concerned about their attitude. If they were to release a decent open source Linux client with compatibility layers (just free ride Valve for now...) and commit to maintaining it, then I guess I am on the boat. Last time I checked the process was not very polished and games could be outdated.

I would love to do that, but I have always had trouble getting it to work well with GOG. Maybe it is something odd with my systems, but I have found it is easier to just download the games from alternative sources than GOG and run them in Lutris, setting them up manually.

Heroic game launcher has huge flaws, one of this is to update a videogame, you have to download another copy of the game. Updating baldur's gate on my steam deck takes 180gb.
