I've asked them about their definitions, about how they'll manage requests for access to their "woman's group" from trans and non-binary people (trans with and without GRCs), and if they're planning to use self identification into the protected characteristic what risk assessments and impact evaluations they've done to ensure this doesn't affect their aims.
Also about whether they intend to record gender and sex, and if not how are they going to assure the safety of trans and non-binary people and what risk/impact assessments they've carried out to ensure no harm is done if sex is deliberately or mistakenly misreported/concealed by patients.
If they're intending to not record sex, how are they ensuring there is no financial/administrative burden in asking unnecessary questions repeatedly about pregnancy (for example) in populations where that's not a possibility (ie men, mostly unambiguously male), and what risk/impact assessments have they done on populations vulnerable to unclear language, eg ESL, learning disabilities, dementia.
Similar questions re: women's health - how will they ensure appropriate inclusion of gender diverse females and if answer is gender neutral language, what risk/impact assessments have been done on groups vulnerable to unclear language.
I suspect the answer is no impact/risk assessment outside that very small community of interest.
