That sounds like an unfortunate mix of two "feature"s that are
mutually incompatible.  Perhaps those who thought auto-fetch was a
good idea didn't think through the implications, and also it is
understandable that those who never thought auto-fetch was a good
idea would want --force-with-lease to default to the remote-tracking
branch.

This description is not accurate.  Only those who do not to specify
what is expected and instead use the remote-tracking branch are
affected (but these random "git fetch" clobbering the
remote-tracking branch is sort of known and expected).

I do not think I would mind if these two new lines were added one
paragraph above, i.e. where "--force-with-lease=<refname>" form is
described.  It clearly says "... as the remote-tracking branch we
have for them." and that is the best place to say "This option
interacts badly".
