I find it very bizarre. There are a number of anomalies in the whole process because of how it is set up, but a gender recognition certificate may be applied for only two years after someone has transitioned into the acquired gender full time, so there has already been quite a long time to try to sort out other issues. Amendments 13 and 14 would simply end the spousal veto, so that people who transition do not have to rely on their spouses to give approval. Some spouses will not give permission for that to happen.
Amendment 16 deals with marriage and birth certificates when there are transgender issues. It argues that replacement marriage certificates should be available for people who have transitioned, so that we do not force them to be outed every time they have to show a marriage certificate. We would reissue a marriage certificate with the original date and new names. That is a simple thing, but it will make a big difference. Not everybody who has transitioned wants to be known as somebody who transitioned. Many people just want to be known by their new name and new gender, and they do not wish to explain their past in every case. They already face that often enough when dealing with various institutions and medical issues. We should not force people to out themselves every time that they need to present a marriage certificate.
