Rule to allow tearing for all games launched via Steam in Sway and Hyprland

So both Sway and Hyprland now support Waylands' tearing protocol. I was wondering whether it is possible to create window rules for these WMs that allow tearing in all games launched via Steam. Something like: For Sway for_window [class="steam_app_*"] allow_tearing yes

and for Hyprland windowrulev2 = immediate, class:^(steam_app_*)$

Does anybody know whether something like this would work? You know, instead of having to create an entry for every single game.

Edit: As mranderson17 said, allow tearing isn't in the latest release versions of Sway or Hyprland at the time of writing.

Edit2: mranderson17 gave what could possibly be the right answer:

For Sway for_window [class="steam_app_.*"] allow_tearing yes

For Hyprland (maybe) windowrulev2 = immediate, class:^(steam_app_.*)$

I haven't tested it yet. But unless you think he's wrong give him your "thumbs up".
