It was never intended to be enforced. In fact, the whole reason for
specifying a blob type at runtime was so blobs in single table could
have different blob types. One of the models I used in designing the
feature was marked up text -- straight Ascii, runnoff, troff, tex --
intermixed in a document table with filters to fetch whatever target
format was required.

The engine's responsibility is to store and fetch blobs, and if asked
politely, find a filter to go from A to B. It was never intended that
the feature would restrict usage.
