Why are client scripts not working in mobile agent?

[Brianlion]

I have a client script to hide a choice value for a list field depending on the assignment group of a user. The script works fine on desktop but won't work for mobile agent (not classic mobile). I selected "All" for the UI type in the client script configuration and still no luck. I read that client scripts may not work for mobile agent, but I am not sure. If they do not work for agent, is there another way I can achieve this functionality? Client script code posted below:

function onLoad() {
//Type appropriate comment here, and begin script below
var assignmentGroup = g_form.getValue('graffiti_assignment_group');
if(assignmentGroup == '8b18132bdbec0050eb4700b5ca9619b4'){
// Do nothing
}
else{
// Remove RAB option
g_form.removeOption('resolution_code', 'RAB');
}
}

That's cool and I don't really disagree with the concept in general, but entirely limiting that ability seems like a weird move.  Even super short forms might require some sort of logic.
