It's because some people's definition of "barely playing" is very different from others. For them, "barely playing" means "one M+10 a week, couple raid pugs, buy a high level BoE from AH" or something like that - not realizing that it's beyond the reach of people who will truly benefit from this update.
For those truly geared, all this does is give them more Residue from scrapping ilvl 400 Azerite gear instead of 385. They couldn't care less, especially since most of that stuff will be irrelevant after 8.2 anyway.
