@henry2cox confirmed via https://man.netbsd.org/xargs.1:
-r Compatibility with GNU xargs. The GNU version of xargs runs the utility argument at least once, even if xargs input is empty, and it supports a -r option to inhibit this behavior. The NetBSD version of xargs does not run the utility argument on empty input, but it supports the -r option for command-line compatibil- ity with GNU xargs; but the -r option does nothing in the NetBSD version of xargs.
