Very active. I use a fair share of them, and they are updated regularly.

On the rare occasion that something breaks (Seti_UI theme, mostly. But to be fair, I installed it when it wasn't stable yet), fixes are often published the next day or at most in the next handful of days. In the meantime you can just disable a plugin and go ahead. But again, it happened rarely to me.

The only problem (that I'm aware of, correct me if I'm wrong) they ran into was the whole deal with Kite basically paying some plugin devs to hide spyware into their code. But that has been handled and solved, and lead to the creation of basic guidelines for plugin developments and extensive discussion of the forum. Devs were very responsive.
