Andrew,

    Without being able to set a value in a template, you have to change
    backend scripts to enact this change, even though nothing in those
    templates needs to change. If there is a customer feedback script called
    feedback.cgi, your CGI programmer needs to care about the site layout and
    design to pass in a variable.
    
    You will run into similar problems all the time if you design your app
    using an MVC style.
    
    Does this help shed some light on why this functionality is desireable?

     It sounds like you are changing the functionality of the
application when you make a change to the feedback template.  
     A simple mail-form script would not need changed when you update
the html form template if it is written correctly.  If you are using a
mail-form script and you have to update your "backend" then I suggest
you re-write your mail script to be dynamic based on what is in the CGI
object.  If you are familiar with the associate feature in
HTML::Template you will not have to worry about the way the form data is
passed from form to form unless you have to act on the input.  In that
case, of course you would need to change the backend to work in the new
way.  
     Do you use CGI::Application?  You do not need to worry about the
layout of the template nor do you want to set values in the template. 
You have to break your paradigm.  I highly suggest looking into
CGI::App.  It is a great way to use HTML::Template and would help you
gain more control over your apps.

    
    Humbly,
    
    Andrew
