NIH can also be great if you only need a subset of a "mature" dependency but you need to really nail it. Since it is a solved problem you'll likely find ample documentation, algorithms and code examples so there is much less that can go wrong than in a greenfield project. At my last job we rewrote InfluxDB as it as was too resource-hungry for our embedded device and the result was fantastic. 10x the time series storage at a fraction of the memory and CPU utilization, much more robust and flash-friendly.
