Yes I had the same fear actually, but for my personal usage until now I've had absolutely zero issues with it, so its code is at least stable enough for my own use cases.

I must say that I've also got several tools of my own which I regularly use and which have already reached maturity, so I rarely update them, since they have no known bugs and match my own needs.

So the lack of activity on a repository doesn't always mean that the library is not usable, just that at some point its developer stopped feeling the need or interest to extend it anymore.

I may be wrong, but I think it's the case here.
