Wildcard domain support for next/image

[okose-me]

Describe the feature you'd like to request

Hello, our project works on more than one domain, we need to add more than one address as a subdomain when we use next / image.

E.g .:
us.example.com
de.example.com
es.example.com

as.

Describe the solution you'd like

Can wildcard support be added instead?

Eg:
*.example.com

Describe alternatives you've considered

Couldn't find an alternative solution :)
