It's seemingly useless as far as I'm concerned.
It's at times a popularity contest--who gets noticed by Microsoft, whoo hoo.
In December 2019, I submitted a post to the FH regarding the now-infamous disk-defrag bug--specifically, watching it "defrag" my nvm-e (complete with passes and %consolididated) during System Maintenance. I even uploaded a screenshot. I was running Insider Build 19041.1.
No reply, no acknowledgement. I felt like I had to blow the dust off of my post when I accessed it again 6 months later. Probably they thought it wasn't legit. Now, it's a known and commonplace concern, people asking whether this is wearing out their hardware, etc. Even more ridiculous, the bug was fixed in a later Insider Build but never transitioned to 2004.
Why Microsoft hasn't done anything with this is a genuine mystery.
