The way I use Lutris today is nothing more than a prefix manager, I click add game, set up my prefix, and install my games manually.

New features will be unlikely, but not entirely off the table if there's a really good reason to include them.

Given this, wouldn't simply bookmarking the last Lutris release that you find acceptable be an easier way to meet your needs?

Or are you trying to guard against Lutris disappearing or retroactively changing old versions?
