I don't know anyone who uses BINARYMIME. Microsoft's MTAs say they do but I've never tried to see if it works.
We did some testing with it and got some really inconsistent end to end responses even from services which advertised it. The idea of saving bytes by not using base64 was appealing.
Back in 2016 I proposed CDAT which is like BDAT but with deflate compression (what gzip uses.) That would shrink base64 to no bigger than the original data, but nobody was interested.

And BINARYMIME is incompatible with the line length limit unless your content happens to have new-lines in the right places or is shorter than 1000 bytes.
Right, the binary data probably isn't text so if it has any \r\n pairs it's just an accident.
