I suspect a lot of posters haven't watched much of the Blues this year, but Beauden was one of their best and they wouldn't have made the play offs without him. I made the comment about a month or so back that people would be triggered when he gets named at 10 for this match and was told I was just trolling, but he has actually been very good this year.
I have no issues with him starting this match, but as people have pointed out age isn't on his side so they will need to have an eye to towards developing a younger player for the next RWC. That said, I am not a big fan of a coaches plans having to revolve around a 4 year RWC cycle, it leads us down the path of anything outside of it is just a "friendly" which would be a bad thing for rugby overall.
