Is this package maintained?

I see that PRs are generally merged, but there are quite a few open issues.
The statement is that this package is used in production in Cloudflare Radar.
Radar is fairly simple in terms of API complexity - it has quite a few endpoints, but all of them are just GET requests used to fetch data.
Many of the open issues evolve around more complex scenarios - different content types, empty responses, file upload, custom headers, etc.
So my question is this - is this the intention of the package owners to support wider use cases than what Radar needs?
Does the team actively investing time in it, or only if it happens to be needed by a feature in Radar?
I really like the package, but I prefer knowing upfront what I'm getting into.
Thanks
