I would like to add a big +1 to this as a basic feature request. I have a scenario in which fields may or may not be changeable based on other state. Affected fields include a select field, a radio field and a text field. Having to code up separate workarounds for each case is a pretty high cost to pay for some pretty straight-forward functionality.
