I doubt it, since they already did that journey long ago and are now adding virtual threads next to ordinary threads that replaced the original green threads. If you put your long running work into the virtual kind of threadpool, a timing sentinel can easily warn you and after noticing that you easily use the normal threadpool instead.

VertX framework had such a sentinel, but migrating code from the async futures to a normal threadpool can be a bit tedious if your design is poor.
