Last I heard, most well informed apologists embraced the CT (catalyst theory), or maybe the MT, (mnemonic theory).
I don't believe that has ever been the case. Of course, I'm not sure there has ever been a significant number of people who could have been characterized as "well informed apologists". But of those I've known, very very few bought into the "mnemonic device" theory. In fact, its original proponent apparently no longer considers it a tenable proposition.
Unfortunately, when you say "catalyst theory" you're making reference to something that manifests itself in very different ways. For example, I believe that the Book of Abraham was produced in the same fashion as the Book of Mormon and D&C 7, but I also remain persuaded that these papyri have a relationship to Ptolemaic Jewish thought and practices, and that an Abraham text did appear on the lost portion of papyrus (the extant portion representing only a mere fraction of the original whole). That, of course, differs from Bokovoy's thinking in a very significant way.
And that's about as much of an answer as you'll ever get from me on this particular message board ...
