Yes though the question is of course what is obvious cf

There are literally thousand, tens of thousands of very simple
characters not encoded. The simplest ones I can think of have only
four strokes to them. The most well known being the rectangle with a
vertical line; and my favourite consists of U+5B50 子 U+529B
力, Zhuang lwg meaning child.
Can anyone think of a 3 stroke character that is on the list of to be encoded?
The point of the above being if even fairly common four stroke
characters are yet to be enoced there should be no suprize that
<U+9F8D U+9580> has not.
