I didn't read through this whole thread but the workaround that I noticed with the macOS version of Teams is to click the 3 dots next to the first message in the thread and select the option "Share to Outlook". Then an Outlook new email window will pop up. The body of that email will be the Teams thread with names and response times listed. You can then copy-and-paste this email body to wherever you want. Don't know if this will work in the Windows version of Teams but seems like it should.
I'll also add my 2 cents that having to do all this just to copy-and-paste a Teams thread with names and timestamps for archival and documentation needs is ridiculous. We should be able to just copy-and-paste directly in the Teams app like we used to be able to do.
