   I think the prototype you're referring to is here: https://gist.github.com/paleolimbot/c42f068c2b8b98255dbfbe379d905607
   
   This prototype is for the tensor extension type, which is more like a tensor as a column in a table and is, I believe the preferred way to deal with tensors since the extension type works with the C data interface and ArrowTensor does not (as I understand it, ArrowTensor is a C++ class and an item in the IPC spec but has little support elsewhere).
   
   The extension type will have C++ support so it should be straightforward to add a wrapper (i.e., the prototype I did probably won't be necessary). It should work like any other parameterized type (i.e., you could use something like the wrapper around `ListType` as an example for how to implement it). I don't remember if that PR has merged yet.
   
   We could also wrap the `ArrowTensor` C++ class, which is I believe what you're referring to. I'm a little concerned that adding support for that particular class is adding support for something that will be deprecated soon and hasn't seen much use elsewhere.
