Look mom, I'm a wizard! I need to project myself onto the astral plane, to appear before the council of middle management! If I don't, I might get fired!

I remember using bare wine to play games before proton. You would have to go and find the exact libraries needed to run the game, install them one way or another, pray a bit, and maybe the game will run with acceptable fps. If it ran at all.

And these days its just plug and play. Dont remember the last time I had to install a game dependency with proton, from steam or otherwise.
