+offered as its preview features. It may take several JEPs and a few release
+cycles for such a feature to become either integrated into the platform or

+support in Vim for syntax related preview features that are implemented. You
+can request it by specifying a list of preview feature numbers as follows: >

+Note that as soon as the particular preview feature will have been integrated
+into the Java platform, its entry will be removed from the table and related
+optionality will be discontinued.
