A late update here: I've merged most of the proposed changes and implementations for ADBC 1.1.0 into a branch [1]. The remaining work is to finish up the C++ implementation and Python bindings, after which I'll propose a vote, hopefully in the next 2 weeks. Any feedback on the API proposal so far would be much appreciated (diff against main at [2]; focus on adbc.h, go/adbc/adbc.go, and java/adbc-core).
I don't expect 1.1.0 to include C# or Rust, but I think this is OK as they are still being brought up regardless.
