If your emulation is going to emulate the hardware (which it should), then flux implementation is much easier than having to do conversions and extra clocking. For example, to add density support to .g64 images you would need to fetch density data for every single GCR byte and adjust the clocking - and guess what? That's still not enough for 100% compatibility. .stx format for the Atari emulators has a 32us clocking window which is not enough for 100%. IPF is also limited in this respect. As an emulation author myself, I definitely would want only 100% compatibility for my emulation if it was possible, and would do whatever is necessary to make it happen.
