Hey @modern-artist-55754 2 reasons so far:
1. We would just like to suppress the display of aspects/tabs not in use. It confuses users that something is broken.
2. Since low code custom model fails to display custom entities, if we want to reuse an existing predefined entity for a new concept, it would help suppress aspects that don't make sense for the concept we are trying to display in Datahub UI. Ideal fix would be to enable custom entities to be able to be displayed in Datahub UI. This is just us trying to work around current limitations.
