The pattern is so overused that organizations that never even tried to amount to something adopted it. Eg I was once at an event organized by "DSP Valley", which was never more than someone behind a desk organizing a few (mediocre) networking events: https://www.hightechcampus.nl/bedrijven/dsp-valley.
Yep! I myself live and work in the area (Eindhoven) that willingly calls itself "Brainport". I hear the word almost daily for ten years and I still cringe.
