Yep, I very occasionally see natural '10x' types who can jump into any codebase or business.... and more often see '10x' types who learn the environment more slowly but then speedrun using their other skills once they are situated. Latter bet is safer, a lot of the bigger fun is year 2, 3. For job hoppers, I often see folks who don't realize they are leaving behind landmines for their colleagues. They haven't had as much of a chance to learn from their mistakes. They learn from inheriting, but often not at a 'senior' level of decision making. So we hire fewer and slower, and work to maintain a team that values doing well at their craft and building ambitious things that take time.
