><noscript/> provides semantic value? Oh, I get it! It's a joke! Very funny.
><noscript/> is all about processing and presentation, and none about semantics.

  Just because the <noscript> element is not displayed for UAs that 
support the scripting languge used, and is for UAs that don't, does not 
make it a presentational element.  A noscript element tells the UA that 
this section is specifically for use only when scripting is not 
supported or disabled.  Defining class or id attributes and setting the 
style to 'display:none;' does not inform the UA that the section is only 
for UAs that don't, or can't, use scripts, even though it may have the 
same presentational effect.
