Core Platform Team/Initiative/Quantify and reduce coupling in MediaWiki Core/Epics, User Stories, and Requirements


 * Perform analysis of tools for measuring coupling
 * Detect and analyze cyclic dependencies (use phpda)
 * Measure code abstraction and instability (use pdepend or phpmetrics)
 * Set up tools for continuous measurements over time
 * Analyze codebase to identify the first areas to decouple
 * Set baseline and target metric for decoupling
 * Refactor code to remove tight coupling in first areas
 * Reanalyze codebase to see next steps
