Other comments

Seems like some work was done for selects in #16161. Probably need the same fix for textfields.

The expected behavior should be that all inputs with the :readonly="false" prop applied, in contradiction to the :readonly="true" property set in VForm, should be editable. VSelect is not working correctly.

I feel like the other way around would be more helpful, but I agree that a child should have the last say. If the resolution makes it that all child inputs have the same behavior, that's a win.

Null or undefined will cause it to inherit from the form, if it's coming from an expression you can use :readonly="expr || null".
