Why doesn't parseWithZod Automatic type coercion of boolean types support ‘true’?

[shutootaki]

If you want to set a bool value for formData, you currently have to do the following.
This seems a bit redundant.

formData.append(‘isTimeUp’, String(isRequired && ‘on’));

Personally, I think that if the string ‘true’ is set, it could be converted to a boolean type in the same way as ‘on’.
Is there a reason to only support ‘on’?
Or is there already a simpler way to implement this?
