Yes, if you're happy with the reactive frameworks there's no reason to migrate. Most people, however, would love to remove their complexities from their code bases. Virtual Threads are much, much easier to program with. There's downsides, like not being able to easily limit concurrency, having to implement your own timeout mechanisms etc. but that will probably be provided by a common lib sooner or later which hopefully provides identical features to reactive frameworks, while being much, much simpler.
