Revert this?

I deleted this, but the reason I added it in the first place is that the linter
throws a warning otherwise. This file depends on the <string> include, it's just
that we can get it indirectly from other files, which I'm not sure it's the
right way to do it. Anyways, this is like this all over the codebase, so I guess
it's fine.
