Yes, but it looked like that was the intent. I'm not saying the
hentaigana should be encoded as atomic characters in that block just
because there is space; I think the SVS approach sounds like the right
one (though I'm hardly an expert on hentaigana). I'm just wondering
what's to be done with all of those code points if they won't be used
for hentaigana, since it seems unlikely that there would be many other
kana that couldn't be handled by existing characters or the proposed
SVSes. Is it possible for a block to be later renamed as something
more general to allow for some non-kana, or even to carve out some of
the empty columns for a new block? Or does the stability policy apply
to block allocations?
