z/VM FTP server has long been able to access the removable media on the HMC. Or an authorized z/VM guest can do it themselves via DIAGNOSE X'2C4' (see CP Programming Services book). But to what end, ultimately? Across the industry, the ubiquitous DVD drive is disappearing. The manufacturers are winding down production. Those devices that need optical media have moved to Blu-Ray. Yet many laptops have neither. Weight. Power. Cost. The most secure delivery of service to z/OS is directly via SMP/E. Corrupted data or MITM interference is automatically detected by the TLS connection. You know the data is coming from IBM and you know it hasn't been tampered with. This story is not finished. Technology will continue to change, risk profiles will continue to change (are the Illuminati or State actors producing 3590 tapes and substituting them?), and so the delivery mechanisms will continue to evolve, just as they have done since the story began.
