In patch https://gerrit.wikimedia.org/r/c/mediawiki/skins/Vector/+/967918 we have added a test to check Vector and Vector 2022 Skin dependency against performance size budgets for styles and scripts.
We want to generalise that approach to be able to use it in more skins (specifically Minerva)
Proposed work
- Upstream the test to core
- Only run tests for skins which have defined a bundle size config.
- Update existing bundlesize configuration in Minerva
