Anecdotal personal experience in safety-critical design:

A team was tasked with modernizing their multi-million dollar decades old test stand. The entire time they were cursing previous engineers for their lack of documentation that made reverse engineering difficult. Then when it came time for them to produce the documentation on their own design, they balked at the idea. I had a conversation with them about how they are screwing over the future engineers just like they were screwed over, but they still maintained cost/schedule pressure was too much to comply. We settled on them being allowed to go forward as long as they set aside a fund source and a date to have the documentation complete. When that date came and went, the documentation wasn't done and the excuse was the funding was used up by other projects. I feel like I owe those future engineers and apology.

I don't think I'd be so trusting/naïve today and would push back harder that if they couldn't get their documentation in order when the design was fresh in their mind, they're even less likely to do so in the future.
