With only a T3 and a JMJ source, I think 𠶮 U+20DAE is out of scope

𡅕 U+21155 is in fact also out of scope, but considering there's a glyph in Sans for some reason (probably for design purposes? turns out 𡅕 U+21155 was added alongside another 46 because it's an approved Korean name character. See notofonts/noto-cjk#80) it's reasonable to also request for one for Serif
