"FSMO Roles" #6 & 7 are handled in Microsoft AD Integrated DNS. So why the fuss over that? You are reading vendor material from a vendor attempting to frighten you into believing you can't "do AD" without their stuff. Pure FUD.
I have setup many bidirectional trusts with no issues. Calm down, take a deep breath and go for a nice walk to sooth your nerves.
