> has well chosen abstractions That's a rather large leap of faith. It's more likely that it has a bunch of abstractions that were chosen early in the project when the maintainers were young, dumb, and eager; that have since shown their age and have been worked around repeatedly; but can't be removed due to being core to the framework and having a large body of applications depending on them.
