For the record, Arnstein lived by the "stem down for the middle line" rule, probably because it was accepted by all the various publishers he worked for. But that was back in the day. Gould's more flexible approach is perhaps more current.
Since I don't have to worry about what other publishers prefer, I stem by the phrase like the top staff of B and lower staff of C. And rather than it being dated or "incorrect", it could be in the vanguard, because one sees this now in the Wiener Urtext editions, for one.
Interesting! The only support I could find for Gould's approach in other engraving books were ones that were over 100 years old.

System in Musical Notation, H. Elliot Button, 1919, pg 18
Pretty much everyone else said stems-down, or at best something like Read (pg 64) saying while it “may go in either direction … the more common practice is to draw it down.” Some hand copying books were more neutral, but there haven't been many hand copying books written in the last 30 years so I don't know how current their advice is. The bottom staff of C I could see being used in a series, but as a standalone bar looks strange to me anyway. My eye ends up doing a double-take to make sure I have my staff positioning correct. All the style guides by various publishers that I can say stems down for that treble B, unless you count Gould as basically the Faber style guide.
John, you preferred the bass staff of C because of the continuation of beaming direction, right? I'm assuming you wouldn't want that center line beaming if the other tuplet had another stem direction like this. This one looks even more odd to me:
