Why isn't bind:value allowed on checkboxes?

[Ocean-OS]

In Svelte, if you try to bind the value of a checkbox input, you get an error. Why is this? If I remember correctly, a checkbox's values are either "on" or its original value. I know this wouldn't be used often (if at all) but why is Svelte so strict about checkbox values being bound that there's an error code dedicated to it?

It's a common mistake to try to bind value rather than checked.
There is generally also no point in binding it because the checkbox does not change it on user interaction.

Is there a reason why it gives an error instead of just a compiler warning?

My guess is that it would not work as intended at all.

Bindings on DOM elements are usually associated with an event, e.g. is the value binding on text boxes based on the input event. If this was not set up for checkboxes, an error may make more sense.

Warnings are usually used if something might not behave quite as intended, often there is also a chance of false positives and in the case of accessibility warnings the functionality might only be partial (e.g. not properly supporting screen readers).
