As long as the RCA sticks to its guns and doesn’t accept YCT semicha as legitimate, things will be ok. Most shuls won’t accept a Rabbi who’s not an RCA member.
I have a friend who got semicha from YCT. He’s a great guy, but I wouldn’t use him as my Rabbi. When he got a job, it was in a place where most of the members of the shul weren’t shomer shabbos, and the youngest person there was over 70. If they stick to those shuls, I think we’re fine.
The fact is that Modern Orthodoxy made its stance. It issued statements against the radical changes that Avi Weiss wants to implement, and is not treating his school as legitimate. Other than that, they just don’t even acknowledge it. Why should they?
