I stumbled today over the question of polygon budget for game engines and how to measure it (triangles vs vertex count). Vertex count seems to be the better metric here, but Blender does not show the “real” vertex count as it matters for game engines. I quickly found an outdated add-on that shows the game-engine relevant vertex count:
Do you think it might make sense to integrate this into your export tools? Maybe not on a real-time basis as done in the add-on as this seems to be quite taxing and freeze up Blender, but as a button for on-demand statistics.
