>there are times when GNU grep is not better suited than sed with ERE Because, among other things, sed has filtering features like based on line numbers, address range, etc that aren't present in grep.

An issue I filed (https://debbugs.gnu.org/cgi/bugreport.cgi?bug=26864 https://debbugs.gnu.org/cgi/bugreport.cgi?bug=26864) led to the manual update about back-reference bugs.
