Transwomen will be automatically protected by any misogyny legislation, because that's how hate crime legislation works. It protects absolutely everyone regardless of status.
It isn't a question of sitting down and determining who is, or is not included/excluded, because hate aggravators are not defined by the status of the victim, but the perception of the perpetrator.
It's why it's still an Islamophobic hate crime if someone attacks Hindus in the belief they are Muslims, or attacks and abuses two heterosexual women holding hands because they are perceived to be homosexual, etc etc. It doesn't stop being a hate-aggravated crime just because the offender was mistaken about the status of the victim.
Misogyny as a Hate aggravating factor is still in the pipeline in Scotland, thank goodness, and Labour have indicated it's a priority for them in England & Wales too.
The supposed criminalisation of "misgendering" you are alluding to was always a complete nonsense and has been proven as such.
