Not attached to the name at all

I propose a component tag be created for tasks relating to the global functions in GlobalFunctions.php as well as global variables to help interested users be able to find and work on such tasks

Example tasks:

• T104501: Fix global variable and function prefixes in core
• T29562: Make $wgVersion a constant
• T249459: Hard deprecate global function wfIsBadImage and remove a release later
• T249061: Hard deprecate wfDiff() global function
• T193980: Write a global function to help assign rights to a user group
• T64713: wfDebugLog timestamp should show fraction of second
• T54129: Globals should be explicitly declared in PHP
• T11968: Reduce use of global and public variables
• T159283: Deprecate non-configuration globals
