While I agree an unknown disabling of plugins, not just noscript (there are others like noscript) is a security concern...
There is a big, yellow banner that appears and stays at the top of your browser, informing you if any plugins/add-ons are disabled. So for me, the 'big deal' is being informed. Then the user can, at that point, disable javascript manually if required. After all, is noscript "special" in some way? More special than another add-on for blocking javascript?
