Incompatibility with Velocity's modern forwarding.

[nkomarn]

It is currently not possible to use Velocity's modern forwarding with ProtocolSupport. When a player tries to connect, the forwarding process breaks somewhere internally and a player cannot connect. Upon switching to legacy forwarding, which emulates Bungeecord's behavior, this issue is resolved. However, modern forwarding provides much better security, which cannot be found in Bungeecord without external plugins like IPWhitelist.

Modern forwarding doesn't work for < 1.13 so i guess this won't be a thing until ProtocolSupportVelocity becomes a thing (So i can transfer data at login state for old versions).

In reference to the velocity issue; Do I correctly understand that this issue here is caused by ProtocolSupport disabling or changing vanilla behavior (with login plugin channels)?
Because that’s about the only logical conclusion I can draw here
