This field is supposed to be off by default, and it is only enabled when
running `git submodule update <path>`, and path is not initialized.

Commit c9911c9358 changed it to enabled by default. This affects for
example git checkout, which displays the following warning for each
uninitialized submodule:

Submodule path 'sub' not initialized
Maybe you want to use 'update --init'?
