In general, the more you can package up into single abstractions, the more someone will have to learn to thoroughly understand your code base. If those abstractions fit the problem domain well, hopefully they will ease the overall cognitive load of working in the system, even somewhat early on, but there will always be some ramp-up time. I'm not at all sure it's a big problem, just something you need to be aware of.
