Can't save grey images with transparency!

I think this format was forgotten when you designed the format.

I am also searching for Lab support.

Typically you can efficiently save grey images with transparency by encoding it as an RGB (plus alpha) image with 4:0:0 color sub-sampling. This will discard the color information and store it as efficiently as a single channel image.

You could use n-Channel mode to store LAB content, though this would not be supported in a compatible way with Photoshop, so I'm guessing that would fall short of what you're looking for.
