I would also welcome this feature - the usecase is well described by chris_overseas above. I would just add that this feature is really useful for pretty much all photojournalistic work under bad and challenging lighting conditions, not just BIF.
I am aware of most of the workarounds described above, but they remain just that: workarounds - and are hardly ideal. EC assigned to the SET button and main dial (as in the firmware update to the 1DX), or even better, by just using the rear wheel directly, as in the other auto-modes, would be quicker when things are changing fast.
The fact that EC for Auto-ISO in M mode has been added to the 7DII and as a firmware update to the 1DX should be proof enough of the validity of this request.
Even my little Ricoh GRV pocket camera has a TAv mode that does this right (yes, there's the issue of semantics whether Manual mode with Auto-ISO is Manual mode at all, which it sort of isn't, so Ricoh are probably doing the right thing by calling it TAv, but I think most professional shooters that have been living for a while think of M as meaning manual control of Shutter and Aperture, as ISO has traditionally been a constant factor anyway as you couldn't change ISO mid-roll back in the film days. But those days are thankfully gone, and so we are presented with new opportunities - it just baffles me that CaNikon have been so slow to adopt this feature, as it should have been there right from the start in the first DSLRs)
Now, having to purchase a 1DX just to get this feature means paying top dollar for a soon EOL camera model that is too big and heavy anyway, and the 7D2 I already have, but its sensor isn't good enough under the really bad lighting conditions where EC for Auto-ISO in M mode would be most handy. That is 5d3 territory.
So, looking to ML for a solution seemed like the logical next step - but no luck, it seems.
I fully respect that the ML community want to prioritize other things, but I think the same applies the other way around; please respect the needs of professional shooters looking for solutions to challenging shooting situations, rather than persuading us that there's no need for this feature :-)
