Only if you don't want to get your hands dirty with the layers you're using.

The trade-off with an abstraction layer is that every layer introduces bugs/decisions which may be a concern. But you can always (if it's open source) tweak the layer(s) below.

Moreover, why not finish the game and make your next project in something new.
