Another advantage is the counting mechanism of a bulk-loader.
Well, one could measure up the needed film length (two-nail-method), but when doing it manually, I just spooled until the film reached the flanges of the spool, by this gaining about 42 exposures. However more modern cameras typically rewind after 36 exposures so that won't make sense with such cameras. Aside from the fact that exposing beyond the film-counter reading means memorizing the number of exposures.
