This makes no sense, both have their place and limits are good! Ossification has a purpose! I often use the metaphor of a tree: leaf = library stem = framework root = platform Write platforms so you can hot-deploy everything including the database and change the turnaround of the iteration to as close to zero as you can! In my MMO engine client I have a couple of hundred of milliseconds turnaround from saved source to running in the engine (platform + framework + library) without any reloading of assets. Same thing on the Server. Only use OS + language (C+ (only string/stream and classes for structure only) for client and JavaSE for server) and build everything else yourself except if there are libraries built by one person (personally I use JSON and DNS4J for Java and GLEW + SoftAL for C, all of those are at the edges!). Everything else is a recipe for long-term disaster!
