It can - Kwi also embeds into Yakuake :-) At the moment this takes a little bit of fiddling still, but hopefully it will be simple to choose soon.
Can you elaborate on that? I use yakuake and I don't understand the connection. (I am merely a user not a software development or engineer)
AFAIK Yakuake uses the Konsole part for the terminal. And it's lacking some of the newer fancy features that more modern terminals (Kitty, Ghostty) support.
