If you want them to display correctly in Emacs youʼre going to have to
use the sequences in emoji-zwj-sequences.txt and emoji-sequences.txt

Yes, because of the U+2640

The field in emoji-zwj-sequences.txt is called 'descriptions', and I
think theyʼre not intended to be normative in any way, so probably
best to use the base codepoint.
