This has been on my mind for a while, but based on T220986: [Regression] Increase in APCBagOStuff::get cost it seems like a good idea. We currently cache literally everything in extension.json in APC, even if its not performance critical. A good example of this is stuff that's only needed during unit tests, like ParserTestFiles (which really should be autodiscovered) or QUnitTestModule. If someone wanted that attribute, we could re-read all the extension.json files again when asked for the lazy loaded attribute, since performance isn't critical during tests.
