I know this might be better implemented as a TPA-RFC, logically, but i feel we already have rough consensus on this. The last request for a VM that came in (#40070) really demonstrated to me the reason for this deprecation: `tekesicola` is certainly a nice-looking name, but I have no idea what it means or why it was picked. So it would make someone unfamiliar with the history of that machine to actually know what it's for.
