One other reason that manufacturers don't go as far as they could relates to the co2/emissions targets that they are managing to. If I remember correctly, the 1M has a co2 output of 224g, which is just below the UK threshold for higher tax (at 225g+).
Agree that commercially BMW may not want the 1M to exceed to M3's performance by too much either. I personally wouldn't want to go down the remap route as I feel the 1M already exceeds my driving abilities but just saying that mild remaps are likely to be within the tolerances of rest of the 1M's hardware. Just a personal view - happy to hear others.
