Not really. They have existed since extremely long without being bound to
ideographs or sinographic requirements on metrics. Notably their baseline
and vertical extension do not follow the sinographic em-square layout
convention (except when they are rendered with CJK fonts, or were encoded
in documents with legacy CJK encodings, also rendered with suitable CJK
fonts being then prefered to Latin fonts which won't use the large
siongraphic metrics).

If they were like emojis, they would actually be larger : I think it is a
case for definining a Emoji-variant for them (where they could also be
colored or have some 3D-like look)
