Currently, artifacts are expanded w/ ZipToSrampArchiveRegistry/ZipToSrampArchive in multiple locations client-side. See:
- shell's UploadArtifactCommand and DeployCommand
- ui's ArtifactUploadServlet
- wagon's SrampWagon
- server's Maven facade (MavenRepositoryServiceImpl)
Consider moving the expansion somewhere central and server-side.
If the concern was that it's not spec-compliant, consider moving the expanders out of the atom module and create something isolated.
