Groups are going global now because of BTS. There would’ve been a spike even without them tbh. Lots of companies are catering to the western eyes more so Korea.
And looking at some of the recent 4th gen girl groups they are going ITZY’s route with the whole teen crush concept and sound. Apart from Gidle I haven’t really seen a girl group with a straight up girl crush concept it’s like they added another layer to it or are exploring different sounds.
So to answer your question yes.
