To be resolved: is ISSUE-57 [name of element in end tag /] still important?

Is ISSUE-57 still important? 

It is titled: "c14n end tags
"eliminate the need of the name of the element in end tag / make it
optional"
http://www.w3.org/2008/xmlsec/track/issues/57

 This is not addressed in C14N (http://www.w3.org/TR/xml-c14n11/) or XML
Signature Syntax and Processing Version 1.1 work
(http://www.w3.org/TR/2009/WD-xmldsig-core1-20090226/)  

There is only one e-mail on this
