From Seqera platform I cannot add any non AWS S3 bucket. The S3 API is used by many vendors, first of all Openstack swift, used by many institutes (in Italy this is the platform technology proposed by many national resources), and now by most on-premise solutions (DELL, Qumulo, VAST, etc all propose an s3 API).
Being able to add any S3 compatible endoint would be super-useful.
