Correct, I see no way to support this cross Wagon providers. Do we want to retain this issue anyway? Another issue is that ETags are opaque and are not subject to interpretation. I consider the approach taken by Nexus invalid and breaking RFC 7234. A custom header would have been better.

> The HTTP transporter can use checksum implicitly transferred via the {{ETag}} response header: https://github.com/apache/maven-resolver/blob/47edcfe69c4e52ced4cb93d65b7348b5645cdd68/maven-resolver-transport-http/src/main/java/org/eclipse/aether/transport/http/HttpTransporter.java#L526. This feature is called smart checksums.
> The same functionality should also be supported in Wagon.
