Is Java WebStart Deprecated?

I have a hard time parsing the information about jlink, so please excuse if that
is a well answered question. From what I can gather, jlink does create native
launchers (which means that the application and the JRE are packaged and can be
"simply" started on the target machine without a prior installed JRE), is that
correct? If yes, I'm not seeing an option in the jlink documentation to
"cross-compile" for another OS, did I miss something there?

Using the ‘jlink’ tool introduced with JDK 9 will make it even easier for application developers to package and deploy dedicated runtimes rather than relying on a pre-installed system JRE.  Oracle will begin transitioning from the standalone architecture later next year in what will be a multi-year effort.
