A bunch of cassette formats just store the data after demodulation, which doesn't work for cassettes that have mixed audio and data, certain copy protection schemes, or where it depends on periods of silence. Using an audio format like WAV/FLAC helps for computers that used consumer audio cassette media and player. You still need to be careful with copy protection schemes that try to mess with AGC or bias compensation.
Then there are the systems that store MFM data directly onto cassettes, that would benefit more from a specialised format...
