I perceive a disconnect here between the objective and the assumed
mechanism to achieve that objective.

If the objective is "Provide a friendly environment for people starting out
learning Java to get familiar with it", why does the mechanism have to be
"Make changes to the language" ?

For example, couldn't you use JShell to build a sufficiently "friendly
environment"?

$ cat friendly.jsh
double input(String prompt) throws Exception {
    System.console().printf("%s", prompt);
    return Double.parseDouble(System.console().readLine());
}
$ jshell friendly.jsh
|  Welcome to JShell -- Version 23
|  For an introduction type: /help intro

jshell> var x = input("Loan: ")
Loan: 123
x ==> 123.0

Etc.
