So according to the ruling last year you would have to play turtle shell before a person decided to use gensai's RA. Does that ruling still stand as of the 20F rule set?
Re: Gensai and turtle shell
A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

Yes, because of Gensai's targeting being optional.
