Thank you for your detailed explanation — I completely understand your use case now, especially since you're using books as products and authors as brands.

First, regarding your question about industry standards:

In most mainstream eCommerce systems such as Shopify, WooCommerce, and Magento, a product is typically assigned to one primary brand (manufacturer). Multi-brand assignment is not a common default architecture. This is because "brand" is generally treated as a singular manufacturer attribute rather than a relational taxonomy like categories or tags.

So from a market architecture perspective, EasyStore’s current structure (one product → one brand) follows standard eCommerce data modeling principles.

Why we’re not planning to change this

In EasyStore, the Brand entity is designed as:

• A primary product identity field
• A filterable attribute
• A structured business relationship

Allowing multiple brands would require:

• Database schema changes
• Query restructuring for filtering and sorting
• UI/UX redesign in admin and frontend
• Performance and compatibility considerations

Given current roadmap priorities and the broader user demand, this change isn’t something we can commit to at this time.

I truly appreciate you raising this — your logic makes sense from a content perspective. However, from an eCommerce system design perspective, authors are better modeled as tags rather than brands.
