Technically, there could be "hormone issues", in that m-to-f transwomen continue to take female hormones to maintain their physique.....and those hormones do anything But make you stronger than natal women...so, if they wanna be all letter-of-the-law on the contract about hormone therapy, they could yank that outta their butts at her. Would be utterly meaningless in any practical light as to "fairness" to the born female opponents, though.
