DEP 7, incomplete sentence/thought line 28

In [DEP 7](https://github.com/django/deps/blob/master/draft/0007-dependency-policy.rst) at line 28:

```28: ...community and core team that the chosen dependency...```

The sentence just dangles off into space there...

Unfortunately, there's no way to make a line-comment without editing the document and I'm not sure how verbose/specific you want to be here or whether that was just a repeat of the prior sentence that got left hanging accidentally.
