Not so fast :-).  It's not a good idea to use that fallback for
korean-hangul-* although it makes sense to use it for korean-hanja-*.

For korean-hangul-*, the following fallback should be used, instead. So, it
looks like we have to add this pre-defined counter as well.

@counter-style korean-decimal {
        type: numeric;
        glyphs: '\3007' '\C77C' '\C774' '\C0BC' '\C0AC' '\C624' '\C721'
'\CE60' '\D314' '\AD6C';
        /* '〇' '일' '이' '삼' '사' '오' '육' '칠' '팔' '구' */
}

For negative numbers in korean-hangul-*,  we can use '마이너스'   (U+b9c8 U+c774
U+b108 U+c2a4) followed by a space. Alternatively, we can use ASCII
hyphen-minus. Which is better? Well, it may not matter much because I expect
them to be used extremely rarely...

For negative numbers in korean-hanja-*,  I guess in the past, '負 U+8CA0' was
used. Do we want to use it for lists? I'm not so sure. Perhaps, it's still
better than ASCII '-' or its full-width counterpart.

Even if we restrict the range to 0 and positive integers instead of
extending them to negative numbers, I guess not many Koreans would complain.
 How many people would use them for negative numbers?
