It's not the same, though, Deus Ex's vents aren't one-stop transitions from point A to point B. They can be, and often are, an alternative path through a level segment, featuring multiple exits at various points, it's not just a case of obscuring function behind cosmetic interaction. Additionally, they also function as a place to hide in the scope of stealth gameplay. Vents in Deus Ex are a fully-developed dimension of level traversal, whereas Semiurge's Bloodlines 2 video shows a contextual ability leveraging a singular setpiece shortcut, strategically placed behind an encounter - press button, get awesome.
Maybe I misunderstood Wesp5's angle on it, but nonetheless, these are not similar mechanics in anything other than theme. This Bloodlines ability is similar to the wall-breaking mechanic in DX3/4, though, you're correct on that one.
