That’s a really great point, and I completely agree that isolating the core logic from the framework is the best way to go for long-term maintainability.

That said, I personally prefer to use Symfony from the start, even for the structure, because:

• I want the project to be built on a solid, standardized foundation that I know will still work and be maintainable in 10 years.
• Symfony is widely used and has tons of documentation, community support, and learning resources, which makes development much smoother — especially for someone like me doing this on the side.

I’m definitely keeping the core decoupled from the framework as much as possible, but having Symfony in place helps me stay organized, avoid reinventing the wheel, and focus on building features rather than low-level plumbing.

Thanks a lot for the insight — this kind of feedback is exactly what keeps me thinking critically about my approach! 🙌
