I don't think there is a consensus that storing blobs in the database is always the wrong decision. Yes, there are drawbacks, but it really depends on the circumstances, and it might be the right choice.

Suppose, for example, that you were going to make your own implementation of Git. The normal implementation has a bunch of blobs under one directory. There's not much use in manipulating this directory separately from everything else under .git. The blobs and most of the non-blob stuff are only useful together anyway, so you already manage them as a single collection.

It could create problems for certain backup tools, so that's a disadvantage. But it also simplifies application development. So it's not a slam dunk one way or the other.
