The reason is that the Myanmar block was given four empty columns because we already *know* of numerous characters that will need to be added to the Myanmar script to support Shan, Karen, Mon, and other minority languages written with the script. Ending the Myanmar block at U+109F (instead of U+105F) was done very deliberately, after doing an approximate census of what remained to be encoded for Myanmar.
Starting any possible Georgian extensions in that space, in order to keep Georgian contiguous, would end up just making Myanmar extensions be noncontiguous in turn. It would also require redefining both blocks, which is not a good idea at this point. And finally, we try to avoid *starting* a block across a XX7F/xx80 divide, for implementation reasons. --Ken > I noticed that a new Georgian Extended block was tentatively allocated at > 2D00.
