Maybe the comment would have been better off just saying "Wouldn't it be great if at the end of it's life we could bring Hubble back to earth to put it in a museum". Because that's how I read it, it's something I completely support (just like putting ISS into a parking orbit instead of letting it burn up when that decision comes). Hubble is an important part of history and deserves to be preserved; to inspire current and future generations.

Dragging a specific method of accomplishing that into it was kind of unnecessary from GP.
