I'm planning to upgrade Odoo from version 13 to 16, where the eCommerce shop module has some custom code, the original code is based on traditional Odoo JS framework, I plan to use OWL to reimplement these custom codes.

I compared the source code of 13 and 16, and I noticed that the code of Odoo16's eCommerce shop has not changed much.

Does it mean that the eCommerce shop has not been rewritten in OWL V2?
