A developer doesn't become a senior developer until they realize they know nothing and can truly start to learn. As a junior you want to master the syntax and framework. As an senior immediate developer you have mastered the framework/language and you can do anything. You are sure you have found the way and will share and fight for this way over all others. As a senior developer you see more and realize you actually know very little. The stack you mastered is one of many and the one way can be replaced by a number of different ways. As a true master developer you realize the framework/language has been programming you.
