According the the CI, the querystructures target hasn't been supported since Coq 8.5pl3. I'm still maintaining the parsers and fiat-core targets, but I'm not sure if anyone is maintaining the other targets. @cpitclaudel, can you say anything about the state of the rest of the repo?

I think we only support up to 8.9.
