I'm currently running a 1.18 survival server, with ViaVersion and Protocolsupport. These two plugins together, as you would expect, work as my forward and backward compatibility. I actually used ViaBackwards and ViaRewind in the past, but I prioritize compatibility over stability, in this case. I was wondering if there was a way to use Protocolsupport as a "ViaRewind+" of sorts to add 1.6-1.4.7 compatibility, while using ViaVersion and its subset of other plugins as the rest?
No one plays on 1.4-1.6 for multiplayer. Don't do it, it's pointless, and you're going to run into countless issues.
