Advantage of Muse Sounds Edition Libraries?

Can someone explain (or point me to an explanation of) the process by which third-party instrument libraries are specifically adapted to work with Musescore? For example, the description for the VOXOS Epic Choirs library says "Muse Sounds Edition libraries are exclusive versions of leading sample libraries, created in Partnership with leading sample library developers and re-worked exclusively for the Muse Sounds’ playback engine. They feature a single mixed mic position and curated articulations ideal for notation playback. Instruments with true legato or portamento transitions use Muse Sounds’ bespoke legato engine for smooth, connected lines."

I know that one can work with non-adapted VST libraries in Musescore -- I've done it -- so what are the specific advantages of using the libraries featured on Muse Hub and promoted as having been specifically adapted?

Thank you!
