On Ios, there was a valid point over miss-leading customers... there was noting on the Mac, so apart from it being added as a feature, what is Apple's story behind this? You already have the Health stuff in system report.
Im not seeing it on my (2016 MBP) at all. I have a service battery warning (already known). Im wondering if this feature is disabled once you go below 80 percent health? That sounds counter intuitive though.
Edit:
I was on 10.15.4 and didn't realize it. upgraded to 10.15.5 and now it shows up
first machine is back from service replaced top case with battery and keyboard and bottom case ... I assume this will be similar on the other one ... turn around pickup, repair, return less than a week
both MBPs back the other took obviously significantly longer but both had topcase+battery+keyboard replaced while the other also bottom case - wonder how I could check if its the updated or old keyboard
