No need for that.
People on S3 clones need to set the S3 Endpoint env var, which overwrites the S3 Region.
I have an entire how to explaining that with Digital Ocean S3 Clone, but I’m waiting for Digital Ocean to fix a bug in their S3 CDN before rolling it out.
If Scaleway is in a better shape than Digital Ocean, I think I will give it a try and try to base my guide on it.
