[16.0][17.0] product_template_tags: deprecated?

[AaronHForgeFlow]

Product tags are introduced in v16: https://github.com/odoo/odoo/blob/16.0/addons/product/models/product_tag.py

According to comments here, other modules are dropping the dependency to product_template_tags, as long as Odoo provides a model with the same functionality: #1223

Nevertheless, the module product_template_tags is already migrated and available in v17.

The model introduced by Odoo adds tags to product templates in the same way. However, some other features already in product_template_tags are missing, like for example, the hierarchy in the tags.

I think we should keep product_template_tags module, but adapt it to extend the features in standard. Also some migration scripts will be needed, that was already pointed out in OpenUpgrade project: OCA/OpenUpgrade#3880 (comment)

What's your opinion? Any other ideas?

I agree with your proposal @AaronHForgeFlow , does not make sense to keep the model added in the module if it is already existing in the standard.

If we keep the hierarchy functionality I would propose a separate new module for it (ex: product_template_tags_hierarchy or similar).
