Well, what happened at least occasionally for me is that I have a 
current git master checkout (with submodules), then do

$ git fetch ... && git checkout FETCH_HEAD

to switch to some Gerrit change that I want to modify (that happens to 
move submodule references back to older revisions, but I forget to do 
`git submodule update`), then do some modifications, and both

$ git status

and

$ git diff

only show the modifications that I made, not the changes to the 
submodules, but

$ git add -u && git commit --amend

will make the unintended changes to the submodules end up in the amended 
commit, too.

Without that unhelpful "submodule.*.ignore all" configuration, `git 
status` and `git diff` would have shown the changes to the submodules 
too, and would have told me to be careful with the `git add -u`.
