GrpcWeb middleware status - is it maintained?

Traefik Traefik v3 (latest)

I was looking at starting to use the grpcweb middleware, so we can stop running envoy in our stack. But at a closer look the project status is not encouraging. The fork GitHub - traefik/grpc-web: gRPC Web implementation for Golang and TypeScript is not being maintained as last release is on August 2023. The original project was stopped being maintained even earlier.
I tried to take the project locally and to run the tests. After some initial setup (use NODE_OPTIONS=--openssl-legacy-provider and recreate the certificates as they expired in 2024) I was able to get up to 390 tests passed and 8 failed. I am still working to understand why those 8 are failing, they are specific ones (websocket and large unary requests).

I am trying to understand what is the plan with this grpc-web library that enables the grpcweb middleware as I don't see any activity around it. It is great that we have an alternative to envoy and I would really like to use it, but right now it doesn't seem to have any future.
Maybe there are other people using grpcweb or planning to and would like to put in some effort to help steer this project back on track?

Isn’t this a client implementation?

Please note that this repo is in maintenance mode, and we recommend users migrate to the official grpc-web client: GitHub - grpc/grpc-web: gRPC for Web Clients.

Yes, their recommendation is for a client library (or NodeJS). I guess it's because the original improbable-eng/grpc-web had support for both client and go. So they didn't offer no go replacement recommendation, which means the only real option is to stick with envoy.

Looks like this project improbable-eng/grpc-web is really old, created even before grpc/grpc-web, so that's why they recommend switching to grpc/grpc-web (after this one was created and adopted by many). And it looks like it would need a big effort to get it back on track.
On the other hand I found Connect · GitHub and they do have some kind of a proxy - GitHub - connectrpc/vanguard-go: Support REST, gRPC, gRPC-Web, and Connect clients with one server. - it looks promising, even though still in alpha
