Yep, back around 15 years ago when I had data caps I used to use that feature all the time. Not to copy games between PCs, but to have backups in case I reinstalled Windows etc so I wouldn't have to download them again. The feature's still there: Right-click a game in your library -> Properties -> Local Files tab -> Backup game files. It creates sort of an installer with all the files in it. It's less useful in these days of frequent patches though, because the game will still have to download any newer updates after installing.
