the rules provide for gender self-identification without any need to begin transition, or adhere to any testosterone limits as might be applied. thus if Maxine says "I am female" then Maxine is female and is eligible to play as a female, in a female team.
with Kent having set a new standard, any team that doesn't follow suit will be placed at a self-imposed disadvantage. the result will probably be one of more self-identified players. will it signal the end of "women's sport"? depends how far the process evolves, but it may reach the logical conclusion that cricket is played by humans, with no other distinction allowed under the rules.
