Removing Devices

I’m on my third Android phone now, and appar­ently there is no way to delete the pre­vi­ous phone(s) from my Google Account. The Android Device Man­ager sup­port page tells you how to find the phone and wipe it, but I wiped them before passing them on to new homes. And I don’t care about their cur­rent loc­a­tions. You can hide a device from the list, but not delete it, and I’m puzzled as to why. Do they need a list of all pre­vi­ous own­ers of any device? Why?

And, the page to revoke access to Google accounts from these old devices still looks some­thing like this:

and does­n’t tell you which device or account is meant by ‘Android Login Ser­vice — Full Account Access’. I guess I could turn off each one in turn and see which I need to turn back on, but it should be pos­sible for Google to put some identi­fy­ing inform­a­tion there to help with the pro­cess, even if it’s only the date on which access was requested.
