12v3 connector instead of 12v2? What's with the epoxy? (speculation)

A forum post speculates that the 12V-3 connector, an alternative to the 12V-2 connector, is intended for AI-server GPUs and advises readers to stop buying any hardware that uses it. The post notes that datacenter equipment relies on board-to-board connectors, 8-pin EPS, and proprietary connectors rather than the 12V-3 design.
