Sierra compatibility for Dark Planet, Triebwerk, etc.

In the Sierra compatibility article ( Dark Planet, Hypnotic Dance, Symphonic Orchestra and Triebwerk are declared compatible with Sierra.

However, the versions given are 1.1.0! All other software are presented with the latest version number. So, why not these? The versions included with the Absolute 2 Collection are 1.6.1.

Furthermore, a bit further down, it is tates “VST Sound Instrument Sound Set Neo-Soul Keys and Synthesizers are not compatible. No update is planned.” Which are the “Synthesizers” referred to here.

Some clarification from Steinberg would be appreciated.
