"Is it just to make collecting a set of concurrent tasks bullet proof?" At a surface level, yeah basically. And ask anyone who's used python's multiprocessing how hard that is to actually get completely right. I don't think structured concurrency is going to be some panacea of multiprocessing at all. It's to address code you'd see in golang that's like, make a waitgroup, fire off N goroutines, wait for success and gather errors. That code is not incredibly fun in Java right now. w.r.t. async/await, imo the beauty of virtual threads is that you've no longer got function coloring, and the "await"s are free, implicit, and performant. and of course you're never precluded from using higher level application locks that have always been there, including synchronized now. Also, specifically w.r.t. gui programming, I think Java is unfortunately kind of stuck. JavaFX has been put into the back of the closet, Swing is completely ossified (though tbh I still like it), and what energy is there behind any non-electron/web GUI development anymore anyway? In a world where vscode, one of the most popular new "IDEs"/IDE platforms, is written in a frickin web browser, and mobile apps dominate a huge % of what constitutes "native" GUI development, I don't really blame Java for not prioritizing it beyond keeping Swing working on e.g. hiDPI displays and so on.
