Does this also mean that Bean<T> instances can be registered at runtime?

If so, there's maybe one common use, although it's a pretty restricted
version of "runtime"; the ability to register a Bean<T> and/or do
other things extensions typically do from a ServletContainerListener.

The reason to do those things from a ServletContainerListener is that
the ServletContext is available then, which in turn allows one to read
WEB-INF/web.xml. There are a number of requests to have the
ServletContext made available in extensions, but that's clearly very
difficult to do.

So if the ServletContext can't come to extensions, maybe extensions
can be brought to the ServletContext via this way?

Kind regards,
