Good news, but the bare minimum, really.
No need for a commitment to annual/regular review, since there will never not be a time when men are women.
Sex recorded at birth could include athletes with a male DSD.
It being rugby, I am very uncomfortable with women who claim to be men playing with or against men, even if they accept the risks.
There shouldn't be any need for a transgender policy any more than a star sign policy because sport is played with the body.
Having said that, the policy is a million times better than World Athletics proposals, so I congratulate Scottish Rugby.
