Ok, just got off the phone with Mike from TM. He said that they have made some small modifications to the swing hitch over the last few years, but the purpose of those was to prevent the types of hitch damage seen in the aforementioned thread. As a result, he said that, as long as the TM was closed, and the ground was smooth without risk of a sudden drop or other sudden stress, then it should be absolutely fine to do what I'm doing. Seeing as I'm inside my garage (perfectly smooth floor) with the closed TM, it seems like I'm safe.

Obviously, this is something that can only be done in limited and set circumstances, but my set up seems to be one that allows for this.
