[Feature Request?]: Support for multi tenant architectures?

[askides]

Sometimes for architectural reasons you need to structure your app with a domain and many subdomains:

1. https://example.com
2. https://app.example.com
3. https://user.example.com

This is currently something feasible only in Next.js as even Remix does not support it natively.

Next.js leverages on his middleware to handle such a feature.

The question is, are you guys in plan to build a general middleware to handle this kind of solutions? This would be really a game changer for me and finally a way to move out from Next.js which is definitely became too complex to handle for simple stuff.

I would love to contribute in case.
