Which is what a checkbox is. A switch element seems needlessly duplicative. A checkbox and a switch have the same purpose. I don't mind it entirely after all we have plenty of block level elements that do the same things as one another. This just feels like a solution in search of a problem.

Not really. A checkbox toggles between two binary states of a single option. A toggle switches between two different options.

UI design isn't simple. You can't just pick basic options. Getting it right takes a lot of effort.

A switch is not for choosing between two options. It has two states, on and off, and it should be named in a way that makes sense with that in mind ("Dark mode" not "Dark/Light").

A checkbox can actually have 3 states, checked, unchecked, indeterminate/mixed.
