BINARYMIME was defined in 2000 to avoid that issue, and invents a new BDAT command that uses a byte count rather than escape sequence, so the message body can be an arbitrary sequence of octets. Gmail, hotmail and icloud/ support it, Yahoo and AOL don't, but I've never seen client software that would take advantage of it.

Zmailer did too, but all told it seems like one of those RFCs where the specification's reviewers outnumber its implementations.
