I think you’re over-generalizing from your own experience. One might be downloading a blob, and receiving the content-length up front but the data in chunks. One might be storing a large mutable set of integers as a bitmap. (I’m not thinking specifically of updating a blob via SQL, just of use cases for partial updates of blobs.) A fun but impractical use case would be to implement a VFS that lets you store a SQLite database within a blob in another SQLite database.
