In looking at my copy of D14.1, the Figure 6 prequalified joint details appear to be the same as the D1.1 prequal joints. However, I did not make a side by side comparison and I did not read through the rest of the code.
Also, D14.1 Section 4.10, on Joint Qualification, does not mention D1.1 joint details as being acceptable.
To be safe, I would advise you to follow the D14.1 details and consider any identical D1.1 details as coincidental, at least for the time being.
