N = 16 developers. Is this enough to draw any meaningful conclusions?

That depends on the size of the effect you’re trying to measure. If cursor provides a 5x, 10x, or 100x productivity boost as many people are claiming, you’d expect to see that in a sample size of 16 unless there’s something seriously wrong with your sample selection.

If you are looking for a 0.1% increase in productivity, then 16 is too small.

Well it depends on the variance of the random variable itself. You're right that with big, obvious effects, a larger n is less "necessary". I could see individuals having very different "productivities", especially when the idea is flattened down to completion time.

Individuals do have very different productivities, but they are measuring the productivity difference across a single individual.
