These features are explicitly to make teaching Java as a first language easier. From https://openjdk.org/jeps/463

Goals:

Offer a smooth on-ramp to Java programming so that instructors can introduce concepts in a gradual manner.

Help students to write basic programs in a concise manner and grow their code gracefully as their skills grow.

Reduce the ceremony of writing simple programs such as scripts and command-line utilities.

Do not introduce a separate beginners' dialect of the Java language.

Do not introduce a separate beginners' toolchain; student programs should be compiled and run with the same tools that compile and run any Java program.
