I'm toying with the idea of writing conflict scanner plugin (perhaps "mu" for early binding). Would scanning all plugins' respective composer.json files for dependencies, gather their version numbers, and the load position/priority of the plugin help point out? The plugin could then notify WordPress users of compatibility issues of shared dependencies. Even better would be to notify the plugin author if they are in conflict (when the site is running the latest version of their plugin and it's a victim of latent loading that conflicts with another latest version plugin). Perhaps that would encourage authors to synchronize?
