@adamsilverstein created a PR to add Wappalyzer detection for the new Web Worker Offloading plugin – https://github.com/HTTPArchive/wappalyzer/pull/71 which was merged already
@benni had a question to the plugins. LCP priorization. Sometimes the LCP element on a webpage is text that uses a web font included via CSS. In such cases, the text can only be rendered after the font has been loaded, which can delay the LCP, I think? Would it be possible for the ‘Optimization Detective‘ plugin to detect when the LCP element is text and automatically preload the font in the section to improve performance? Or maybe the ‘Image Prioritizer’ plugin could be renamed to ‘LCP Prioritizer’ and expanded to handle this optimization for text elements as well?
- @adamsilverstein advised this is covered in https://github.com/WordPress/performance/issues/1313

@mukesh27 As part of the improving the calculation of sizes work, I’ve started implementing the new approach to the existing work so we can easily update it with the latest changes. The PR will be open soon, but before that, https://github.com/WordPress/performance/pull/1623 needs to be merged to ensure we have the latest changes on the feature branch.

@swissspidy just merged a GB PR yesterday & opened another one today, working on the next one

@flixos90 No update, the only outcome for now was https://github.com/WordPress/performance/issues/1583, which is ready for development – and marked as “Good first issue”, so if you’re a new contributor and you see this, this may be a great issue to get started!
