Yes, you're right...I can reproduce a change of ID when deleting an object
and re-opening a scene. However, I would not dismiss the object GUID, which
appears to persists between sessions despite the change in the object ID
value. In the below snippet the sphere object changed ID but not GUID.
# Name: cylinder
# ID: 114
# GUID: {090F2A9A-D1FC-4112-ACC5-9345BEB48954}
#
# Name: disc
# ID: 92
# GUID: {D03EF191-3962-4540-929D-F5438CE59D79}
#
# Name: torus1
# ID: 68
# GUID: {1AC14CC7-1175-4E30-9CDD-BC0C0C1DE6EA}
#
# Name: sphere
# ID: 80
# GUID: {CC63558A-D5A3-4F55-8621-6D428FE2743A}
# --------------------
# Delete cylinder, save and re-open scene
# Name: disc
# ID: 92
# GUID: {D03EF191-3962-4540-929D-F5438CE59D79}
#
# Name: torus1
# ID: 69
# GUID: {1AC14CC7-1175-4E30-9CDD-BC0C0C1DE6EA}
#
# Name: sphere
# ID: 99
# GUID: {CC63558A-D5A3-4F55-8621-6D428FE2743A}
