I don't believe thats a work around.
In my eyes thats developing my own application but using the WA tools to apply the programming functionality.
I've never once used the wizards that come with the software as I like to put my own stamp on the look and feel of my sites / applications, and by applying the server behaviours to my own pages I feel I am more in control of being able to add bespoke functionality above and beyond the extensions.
But thats just me....
