If you're a fan of cloud gaming, you may want to take a little look into Netris. The developers say it's a GeForce NOW alternative, one you can self-host with it being open source. They're also keen to highlight some Stadia-like elements of it too.
TL;DR: Simultaneous library sharing. Before, only one user could use a library at a time. Now, up to 6 users can simultaneously play any game from the same library.
This is what Netris is touting users to exploit when they say:
Steam Library Sharing
Grant access to your Steam library, so everyone on your team can join in on the fun without additional purchases.
I haven’t really been keeping track of it for a few years, what’s changed that made it better recently?

Not correct. You can only have as many users playing the same game as you have licenses.
True. But I’m not saying otherwise.
Neat, now my family can play non-split screen games
