I could use (and have used) Körber/HighJump Advantage Architect in production, and yet that's nonetheless so far from notable that Körber's own Wikipedia page doesn't even bother to mention its acquisition of HighJump and the software products thereof, let alone the proprietary graphical programming language which HighJump's customers use to configure and customize their flagship warehouse management system.

Needless to say: production use ≠ notability, for very good reason.
