Huh, I’ve not heard of this, though it doesn’t surprise me.
In the area where I grew up (waaay out in the sticks, with no easy public transport access to the closest AEC office), the AEC tended to send people out to your home on your 18th birthday (or soon after it) and enrol you on the spot. This was decades ago, though, before you could do any of it online.
Did I speedrun a midlife crisis in my 20s? 🤔 Never did pickleball, but that’s pretty synonymous with retirees over 60 in my corner of the world.
