The 7th court makes this moot

Gov. Kate Brown has signed a bill that will make it easier for transgender people in Oregon to shield any updates they make to their birth certificates, a process typically conducted through the court system without privacy from public view.

The measure, which takes effect next year, makes Oregon the second state after California to adopt laws specifically designed to help mitigate potential discrimination against transgender individuals from employers, landlords or anyone else who is otherwise able to dig up birth-record changes through public record.The new law eliminates the requirement that changes to someone’s name or gender identity must be posted publicly by the courts. It also allows court cases involving gender identity changes on birth records to be sealed.

The 7th says gender flipping is fine, self declaration is all they need.  So this law is simply confirmation.  So, for example, the Oregon Ducks girls softball team can, en masse, declare themselves temporarily men and avoid playing a particularly difficult  game.  No need to check birth certificates.
