Multisite on different domains

[petira]

Grav now supports Multisite at the subdomain or subdirectory level:

1. Subdomain

https://example.com   -->   /user/<main>
https://subsite1.example.com   -->   /user/env/subsite1.example.com
https://subsite2.example.com   -->   /user/env/subsite2.example.com

2. Subdirectory

https://example.com   -->   /user/<main>
https://example.com/subsite1   -->   /user/env/subsite1
https://example.com/subsite2   -->   /user/env/subsite2

However, I would welcome the possibility of operating the environment on different domains (languages, countries, products, etc.):

3. Languages

https://example.com   -->   /user/<main>
https://example.cz   -->   /user/env/example.cz
https://example.fr   -->   /user/env/example.fr

4. Products

https://corporatesite.tld   -->   /user/<main>
https://product1.tld   -->   /user/env/product1.tld
https://product2.tld   -->   /user/env/product2.tld

Would it be possible to implement support since Grav v1.8?
