I've seen the pendulum swing between duplication and abstraction a few times in my career, and I'm currently on team "it's usually not that hard to find a good abstraction up front."

IMO it's easier to inline a bad abstraction than it is to consolidate a bunch of subtly different things that should have been abstracted from the beginning.

But I expect people's opinions on this differ wildly based on their personal experiences. Just my anecdotal take.
