Thanks for the question! At the moment, Template Kits are intended to be a design layer that doesn’t include additional functionality. For that there are still themes and plugins. If you are building templates for WooCommerce, and that is a dependency, I believe that is inline with the requirements but it must be part of a complete kit with at least 10 templates.
If I understand correctly what you’re thinking of doing, I don’t believe it would be accepted on its own.
