WK is a bit peculiar with that stuff though because what it calls “radicals” are not what are traditionally called radicals, but on top of that they’re not traditional components either. For instance jisho breaks down 援 as 一 ノ 又 扎 爪, but in WK the right part is its own “radical”.
At other times WK will use the same “radical” for very different strokes, such as 垂 being made out of the 車 radical (which is in fact completely different) or the spring radical in 寒.
Personally I think it makes sense to break kanji apart when there’s a meaningful sub-kanji to be found, such as in 休 being 人 + 木, but when it’s just about random shapes that are not even always drawn the same way it loses a lot of its usefulness.
I expanded a lot more on this topic here: It feels like WK somewhat loses its way partway through
