The filesystem, backed up by git, ought to be perfectly fine for serving text content. It will be interesting to see what happens if they add a lot of images and videos and git starts choking. The main benefit of adding a RDBMS in this scenario would be being able to run indexed queries using SQL. The text content itself wouldn't benefit much, of course, and would be better off with something like SOLR for search. But there will probably be dates and other loose metadata that is ideal for a RDBMS. If the content in the filesystem ends up with associated metadata in a RDBMS, they may wish they had just put everything in the RDBMS to keep it simple.
