It's been about 2 years since my previous post here. I've been busy working on a few client projects. As a consultant, I'm naturally inclined to accumulate a toolkit of tech (technology & techniques). In the domain of technology, where all levels of the solution stack are subject to change, keeping a toolkit while moving from project to project is a challenge.
As desirable features emerge in other libraries, the Framework would need to integrate the new feature. If a library is no longer desirable, it may be difficult to decouple from that library. A Framework has inertia. Once a Framework gains a community, it has an obligation to keep a feature set out while maintaining a simple interface. This often has a cost of complexity & loss of freedom to provide additional functionality.
As any software project (Frameworks included) is used & as new tech emerges, the idioms of the project often change.
