You think you need that, but you cannot know it, because you didn't used
Ada and have no experience to realistically estimate the amount of checks
an Ada compiler would introduce in your, not yet developed program.

I don't see any difference, unless specialized non-dense matrices are
considered.

Same here. Multi-channel images, sequences of images, scenes can be seen
and implemented as  arrays. Again, unless some special hardware is in play.

I don't see a great need in that. Usually the type of pixel (grayscale,
tricky color models, separate channels etc) influences image operations so
heavily that the common denominator might become too thin to be useful, at
least in the case of image processing.
