I think this is an oversight, because this modification destroys some
code.
When compiling them with JDK 9+ and using the -target 8 option instead
of -release 8,
the generated class file crashes when running in Java 8.
Which is exactly why compiling with "javac -source $OLD -target $OLD"
*without* setting the bootclasspath was not a recommended option and
started generating a warning as of JDK 7:

IDEs cannot detect this error because there is no @since document.
Therefore, I think it is important to add @since to them, and they
need to be back ported to Java 11/17.
The solution to a misconfigured build is to configure the build
properly, which includes using --release $FOO where available.
