From w:Adobe Flash:
Adobe Flash (formerly Macromedia Flash and FutureSplash) is a discontinued[note 1] multimedia software platform used for production of animations, rich internet applications, desktop applications, mobile apps, mobile games, and embedded web browser video players.
Flash has been de facto EOL since 2020 (that's about five years or so as of now), and yet PictureGame, PollNY and QuizGame have some Flash-related code: the LightBox (loaded from the SocialProfile extension, RL module name ext.socialprofile.LightBox) and the Flash support module (which provides the isFlashSupported() global method, also loaded from SocialProfile; RL module name ext.socialprofile.flash).
Doing this will clean up the relevant codebases a bit, allow to kill off one completely unnecessary ResourceLoader module and thus theoretically reduce the payload size a tiny bit.
