I mean, my daughter goes to public school, leading a mostly "cookie cutter" existence, and several of her peers who she interacts with there have memberships in a swimming pool of some sort or another.
Given that we wanted her to be able to swim with them, we paid a professional to give her swimming lessons.
She's now 11, but any time in the last ~5 years, tipping over in a canoe or kayak would not have been fatal for her (even without a life vest).
