The point about increasing levels of abstractions is a really good one, and it's worth considering whether any new code that's added is entirely new functionality, some kind of abstraction over some existing functionality (that might then reduce the need for as new code), or (for good or bad reason) some kind of copy of some of the existing behaviour but re-purposed for a different use case.
