idk, it’s just one line to install every program you need and has a LOT more selection.

It is, but it already has all the services that most would use with big QoL features compared to Redirector. Namely quickly adding and removing instances, and quickly enabling and disabling redireciton for specific services. And is a lot easier to use in general especially for people who don’t know regex.

Plus Libredirect has a few features that redirector doesn’t, the ability to redirect to multiple different instances, and the ability to redirect embedded content such as any embedded youtube videos on any other website.
But as you said, redirector is more flexible if you need it for something other than the ~20 services that LibRedirect handles.

I’m pretty sure they have, I was already playing csgo on proton some years back.
