There are enough people who still identify as Yugoslavs in some way that articles can be written about this as a thing. However, as one who speaks BCMS and Albanian and travels the region for months each year talking with random people about these things, my own experience is that is merely a subculture, not anything representative.
A lot of people going abroad in the 1990s, or as gastarbeiter before that, were coming from Bosnia, the Sanjak, or Kosovo and they understandably are loath to identify with a state they saw as dominated by the Serbs, who committed atrocities against them. For Albanian speakers, Yugoslavia was a Slav-dominated project in general. As for Croatia, significant opposition to Yugoslavia began already by the early 1970s and it only got worse after the 1991 war.
