I assume you’re talking about tracking score on profiles ala Reddit? There’s nothing stopping anyone from making their own client or modifying lemmy-ui to do that if someone really cares.

But honestly, Lemmy has enough bots posting stuff that I wouldn’t want to bring more incentive for karma farming in.

!lemmynade@lemm.ee will have the option to see your own total score if you wish, and there’s other clients and apps that show you that too. However, it’s virtually impossible to see other people’s scores with how Lemmy works at the moment.

I might be wrong, but I think the general consensus is that showing everyone’s scores would enable a competitive karma culture, and that’s not something a lot of us want.

Just use Kbin/Mbin to see the score

How is this critical???
