There are two ways to try and solve the maze: find a path (search, prime &babble) or find constraints by finding walls.
If I need to go from the left to the right In a maze then highlighting continuous vertical stretches of wall from top to bottom will yield bottlenecks while horizontal highlighting along paths yield isthmuses.
Both techniques can be used together
I dig the word isthmus and I like your linked comment about it being somehow dual to a bottleneck (i.e. constraint).
It seems quite related to Wentworth’s mazes. I.e. see the picture https://www.lesswrong.com/posts/nEBbw2Bc2CnN2RMxy/gears-level-models-are-capital-investments
