OK, but you still need to add a warning about data loss.

Sure, you might say, "That's already mentioned" (in the fine print). "The
reader just needs to put 2 + 2 together in their heads." Yes, but
anyway, the document needs to drive home the point more.

Maybe the man page should say so too.

Honestly I don't think it's fine print.
That's essentially the point the quoted paragraph is making.
Being overly verbose in docs is a concern too.
Marking this as done for now.
