When it gets to the point where it does work to produce usable documentation, without extraneous content, with no mistakes, can be checked quickly, and it is faster to generate + check than to write it, maybe. Assuming a stellar history of being correct from the tool.

As it is right now, once you reach the point where you actually need proper documentation to be written to keep things maintainable, these tools have low accuracy, lots of issues, and using them takes longer than it takes a competent person to just write/update whatever needs to be.
