I filed a bug with apple on how broken Disk Utility was in Sierra; I included a screen capture giving a complete movie showing how deliriously broken it was. Apple closed the bug with "not enough information."
Submitting Radar reports now is a complete waste of time, they go straight to the trash. Maybe if you're a recognizable name you'd get an engineer involved, but I doubt it.
Sad that I hear something complained about on certain Apple podcasts and that little qualm of that host is fixed magically a release or two later while real users are ignored.
