This would allow Badlion and Lunar client icons to be visible in-game regardless of which client a player is using. Since Lunar has acquired Badlion, it seems logical to support cross-platform client identification, allowing players to see whether someone is using Badlion or Lunar via a badge on their nametag. This would create a more unified experience across both clients.
TLDR: since lunar owns badlion why not let us see badlion name tag logos as well - or make a tag for both, idk. I know people can still inject (and mostly do) but it gives me Atleast some piece of mind knowing their on a client.
