The post reads (ambiguously so, though) -
"Existing legacy packaged apps in the Chrome Web Store will not be
affected, and those existing apps can continue to be updated without being
subject to these new restrictions."
So, if you already have a published legacy packaged application, you can
continue to update it as usual. You will not lose your users.
