Chromium modularization and resource timing updates

Chromium developers marked completion of a major Browser object modularization effort and advanced an Intent to Ship for Resource Timing access rules. Both items concern core web platform internals that affect maintainability and cross-origin performance data exposure.

Project Bedrock modularization reaches milestones

Chromium announced completion of Project Bedrock milestones that modularized the core Browser object across 120 controllers and eliminated 6900 references. The work restructures a central component of the browser architecture. Developers tracking Chromium internals should note the reduced coupling, which simplifies future changes to the codebase that underpins many browsers.

Resource Timing body size access shifts to CORS

Chromium posted an Intent to Ship changing Resource Timing so that encoded and decoded body sizes plus transferSize for cross-origin resources require CORS rather than TAO. The adjustment tightens the conditions under which those timing values are exposed. Authors of performance monitoring code need to verify their cross-origin resource configurations against the updated requirement.
