Indeed - given that the SR advantage is one of fidelity rather than channel separation, a home viewing version needs only sound good enough (though it's interesting to note that this high quality copy of Fanfare is the only one I've seen that doesn't have the SR logo at the end).

Now, what I'd really like to see is a logo for 70mm 6-track stereo. I've no idea if one was ever made, but for my own amusement I put my own together using the audio from one of the Dolby trailers. If you have a section for unofficial clips I guess you may want to include it...
