Did Date and Darwen's “Third Manifesto” have a lasting impact?

Question

In 1995, two DB theory researchers, C.J. Date and H. Darwen, published a text with the rather impressive-sounding name "The Third Manifesto" with their ideas regarding future DBMSes, which would better harmonize a relational model with object-oriented programming, including user-defined types.

It is my understanding that object-relational DBMSes has been mostly/entirely abandoned as a subject of research. So, has this manifesto had a significant impact on the DBMS world community over the past 23 years? If so, what are the salient aspects of this impact?
