Answer 1

In the Jigsaw Issues List , a module name cannot end with a number. The goal is to prevent authors from encoding version numbers in module names.

Answer 2

JSR 376 is not yet final, and there are several topics that are still under discussion. The latest suggestion for #VersionsInModuleNames is here:
