This is exactly why I like using frameworks and other middleware. With a package manager (in my case, Composer... think Nuget, npm, etc.), I can install 3rd party components, but the existing framework/middleware allows me to write custom code easily if necessary. Like, right now, my data entities are a mix of 3rd party components (for users, and for an implementation of the nested set algorithm), but with my own code extending it.
