I mean, literally everything in the game rewards you in some way, it might be a crappy reward: few copper/silver/gold coins, some useless currency, etc or a good reward: good or even bis items, useful currencies, etc.
You're being showered w/ rewards from the get go. And it's been this ways since Vanilla, moreover, unlike its predecessor WoW did away w/ punishing players for failing to do something. You died? Whatever, you didn't lose any xp or items, you didn't delvl, etc. You're always safe and rewarded.
The only difference between now and then is that most items lost their "face". You no longer remember BiS items by name like you used to, if you cared about such things back then ofc, now rewards come from multiple sources and not just raiding, items also WF/TF and can get sockets, it's not feasible to keep all that stuff in your head. Nowadays you only remember names of REALLY exceptional and/or brokenly OP items, people still remember unstable arcanocrystal from withered jim, heck, I bet some people see that item in their nightmares
And TBQH, I don't think that's that big of a deal. Stats > names.
