Java - What does the jlink option "--strip-native-commands" do? I have found no documentation, but jpackage uses it by default to generate custom runtimes?

I found nothing about --strip-native-commands using jlink --help (doesn't even list it as an option) or even in the docs. I have not found any documentation for it online, but using jpackage -h tells me:

--jlink-options <jlink options>
          A space separated list of options to pass to jlink
          If not specified, defaults to "--strip-native-commands
          --strip-debug --no-man-pages --no-header-files".
          This option can be used multiple times.
          ...
          ...
          If --runtime-image is not specified, jpackage will run jlink to
          create the runtime image using options:
          --strip-debug, --no-header-files, --no-man-pages, and
          --strip-native-commands.

There seems to be nothing about --strip-native-commands online. Using it seems to shrink the runtime a little bit:

34612   ncnotstripped
34568   ncstripped

But I want to be aware of any potential trade-offs. What does "native commands" refer to? What am I removing from my runtime to make it smaller?
