Hello OrganoPleno,
When a sample set producer wants to release a new iLok-licensed copy-protected sample set they need to contact MDA so that we can set up the relevant products and allocate to them the necessary details for encrypting the sample set. In those respects it's exactly the same with v5 as it was v2-v4 (although the actual licensing system is now PACE-based, rather than HASP-based, of course). The necessary licensing package(s) are generated and added into the central master licensing packages file as part of that allocation process.
Hence there are no additional delays, and no more additional central control, in any of those respects, compared to v2-v4. For sample sets that *aren't* licensed via the iLok system, no per-product action is needed on MDA's part, so the sample set producer doesn't need to contact us in that case and can release them independently.
