I fully understand that sentiment, Roger, and indeed I've taken a stab at this myself. But it's a problem with no end, as there are so many ways to do it, each with pros and cons for specific applications. And... 3D is close to irrelevant now, as multiplexed/hyperspectral/timeseries and other multidimensional imaging takes hold in machine learning. My gut says to leave it alone and keep the focus on 2D (but multichannel/multicomponent) in terms of standardization. For 3+ dimensions, HDF5 and cloud-friendly Zarr/N5, Parquet, Feather etc may be more suitable for many new applications, and most 3D TIFF-based file formats are already quite proprietary and unlikely to change as they've been extant for years.

Totally happy to be whacked on this, but that's my current take.

Best,
Kemp
