The goal with JEP 330 was to support developers that are at the early stages of learning Java, so options such as -Xlint are out of their scope.
> This patch prevents displaying "Note: Recompile with -Xlint:deprecation for details." and "Note: Recompile with -Xlint:unchecked for details." by implicitly enabling -Xlint:deprecation and -Xlint:unchecked in com.sun.tool.javac.launcher.Main for all invocations.
> Beside avoiding prohibited javac option suggestion notes this patch has positive effect of more verbose compilation diagnostic. Higher diagnostic verbosity is appreciated by users learning Java on single-source programs in java source-file mode.
> Similar case with -Xdiags:verbose was reported in JDK-8248843 and resolved in commit openjdk/jdk/31d0f0d8after review openjdk/jdk/4094
> The patch also provides new test "testNoRecompileWithSuggestions" detecting unwanted recompilation suggestions in java in source-file mode execution. The test cover also case from JDK-8248843 with -Xdiags:verbose
