And non content creators, in the poser user base, will never migrate to Blender just to use the REAL cycles or the Realtime EEVEE engine.

Don't be so sure about that. Migrating a Poser scene into a far more advanced software has always been a thing.

Bringing everything into Blender and learning how to improve your scene by using more and more Blender tools is a big temptation.
