Yes, thanks, Wonderment, for your work here. I'd love to comment at length but must go back to work. I have time, however, for a few thoughts.
As for verse placement, the JB (and NJB?) have worked out a nice compromise, I think. They place the verse numbers at the end of the lines of text for the reason you stipulate and have a small raised dot within the text to indicate just where the verse ends/begins. It takes a little getting used to, but I like the compromise. Does Alter have such a dot?
The "encounter" with Goodspeed was not an in-person one. Some ordinary Bethelite back in 1950 sent Goodspeed a copy of the NWTCGS right after it was released. By that time Goodspeed had retired from the University of Chicago and was living in Los Angeles. Surprisingly, he wrote back. I saw a copy of the letter once. It's kept in the Writing Dept. archives. Basically, he complimented the work and then added some criticisms. When the 1951 revision came out, Fred Franz had implemented most, if not all, of Goodspeed's corrections/suggestions.
I'm not surprised that Cetnar only mentioned a criticism. The compliments were several, something that surprised me a bit, but then Goodspeed was known for being a pretty nice guy.
