I'm so glad software engineering isn't my job. I love solving problems, and I'm somewhat better at using code to do it than my peers (fellow scientists), but I would hate to have a boss/client that says "it needs to do X" and the framework writer (or SDK, ala Android/Xcode) say "no, that hurts my profits/privacy busting".
I've never found something that was impossible to implement in any framework or SDK. Even in Android SDK land, you can easily get access to an OpenGL surface and import the whole world via the NDK. There's nothing limiting other than the OS itself and its mechanism.
Same with Web framework. Even React (a library) has its escape hatches to let in the rest of the world.
Software companies all understand that so its not really a problem. Maybe in companies where the software isn't the main product
