No, StoryLiner has not yet been converted to an extension because it is... tricky, for the least. It is a big add-on, with Python library dependencies, and packing those dependencies as specified by the extension guidelines is difficult, if not impossible.
Not a big deal, though, StoryLiner works very well as a "Legacy add-on" 😁. 

StoryLiner comes in four editions, each adding more features to the previous one to better answer the needs of a particular artistic discipline and to enhance its integration in production.

An overview of the editions as well as their differences is presented in details here: StoryLiner Editions.

Just pick the upper edition and purchase it the usual way. The form will propose you to pay only for the difference between this edition and the one you already have.

StoryLiner release model was initially based on a "Major version purchase" approach. This is not supported by SuperHive Market and a "Support period" model has been introduced recently to provide developers a sustainable model to ensure the maintenance (which, to be honest, is not easy at all to do for some releases of Blender). StoryLiner will align to this model, not because I really want it but by necessity.

With the purchase of a StoryLiner license, you will then gain access to all maintenance updates and new feature releases for 1 year. Then a new subscription will required. Fees will be reasonable, they're not defined yet, but probably less than 50% of the base price per year.

For past customers, and for any license bought before May, 12th, updates will remain free! 

When you own a Studio edition license, you gain access to beta versions of each new release before their official launch. This allows you to evaluate new features in advance conveniently.

The answer is definitely yes ! StoryLiner is designed and written by a professional, for professionals, and it is currently used by several studios, mainly for series.

StoryLiner is based on Ubisoft Shot Manager, a tool that was developed by Ubisoft for the Rabbids Invasion TV series in 2020. It was open-sourced, all along with some other add-ons such as Mixer. At the time, I did an article on how we used it during the pre-production phase, titled Blender and the Rabbids.

Since then, the add-on received a loooot of improvements, such as a storyboard and a 2.5D drawing modules, a render queue, a toolbar... and a a myriad of very useful small tools!

StoryLiner was initially made to be used very early in production. It now can support your sequences up to the step where you decide to break them into separated shot files.
