Make tags use #+ syntax instead of //+ syntax so it no longer looks like a comment. Old style still works but is deprecated with a warning. Using unknown tags is now an error instead of a warning. There is a new token for #+ which consumes the whole line (or until it hits a comment). The tags are parsed like before. There are errors to tell you if you use something invalid in the pre-package-line block.
