Yes, but not in the formal sense. And i don't get why agile and proper documentation should not go Hand in Hand. There are components and class Diagramms that are invaluable for me when i'm joining an existing code base. Even if they are not up-to-date everytime.

State and sequence diagrams are really cool to discuss dynamic flows and identify potential logic holes. UML-like diagrams are way better then to come up with your own representation of this everytime

Time limits, I guess. It's the only reason not to create good documentation. If you fail to deliver on time there's no need in good project docs. More like a chronic desease.

A lack of good project documentation should be treated as technical debt and handled accordingly
