Bootstrap dilemma of `buf`

[Hellseher]

Hi,

Following this issue https://github.com/bufbuild/protovalidate-go/issues/279#issuecomment-3285673884, it was suggested to build buf.build/gen/go/bufbuild/protovalidate/protocolbuffers/go with local buf plugin, while buf needs buf.build/gen/go/bufbuild/protovalidate/protocolbuffers/go https://github.com/bufbuild/buf/blob/v1.61.0/go.mod#L7 to be built giving us cycled dependencies which can't be bootstrapped.

Did you have any lower requirements for buf.build/gen/go/bufbuild/protovalidate/protocolbuffers/go or any other tools where buf is not used as dependency; or, maybe, the procedure of building buf with some optional inputs where buf.build/gen/go/bufbuild/protovalidate/protocolbuffers/go is not required.

Thanks

So buf requires buf.build/gen/go/bufbuild/protovalidate/protocolbuffers/go for our lint rules to check protovalidate options, and we try to keep the packages on the CLI as up-to-date as possible. Do you mind elaborating why/how you are running into this issue, e.g. how you're pulling in the buf tool, etc.? The buf binary and its dependencies should be an isolated concern.
