I think blender has come along way since the showreels of the past. I think it’s important for the blenders brand as blender still has the stigma of being unprofessional and for hobbyists. Besides, it would be really cool to see a really epic blender reel.
Here is a list of work I think should be showcased.

These examples do showcase blender in vfx, motion graphics and animation but this does not showcase archviz so that is a area in which will need a bit of research for.
