The editors at one point had a draft allocation there and forgot that the hole
opened up when that allocation was withdrawn.
Thanks for pointing this out. All things being equal at this stage it is nice
to close off any blocks where that can reasonably be done. As implementers will
never have to revisit them again once they support such a block completely, it
aids their work by limiting the effects of additional character to fewer
blocks.
For that reason alone, and for no other, it might be worthwhile to ask WG2 to
move that character and close the 0300 block.
