Remember, for their early records, the Beatles were working with a 3-track tape recorder. They had to decide from the outset if they were mastering for a mono or stereo product.
The Beach Boys and others approached the problem by recording a mono master, and then filtering a "stereo" mix with some frequencies directed to the left channel and others to the right. The result was far less satisfactory than the Beatles' solution.
