Hi Alyse Hart,
I acknowledge some of the questions here in regards to the documentation. I will escalate this to request that further details are provided.
That being said, Additional information regarding deception in Endpoint is provided in this video https://youtu.be/k2QxyVH--vU by Microsoft's Heike and Dean an MDE product Manager.
To address point 2&3: At the 14.30 mark of the video, Dean clarifies that these Lures or decoys are not actually created instead, the deception technology mimics what that would look like.
Based on my research - I haven't encountered any documentation on limit to the device count for the default rule. _ I will follow up with PG to clarify this.
