We need to figure out if this is OK

[rodaine]

This should be fine if we're requiring Go 1.22+:

go: minimum version required for the language features in the module (that are not behind a build flag)
toolchain: recommended stdlib and compiler to use when building the module (ignored transitively), must be greater than or equal to the go directive (and elided if equal)

It's dense, but the docs on toolchains are helpful.

Starting in buf v1.40 my generated .pb.go file headers changed from:

// 	protoc-gen-go v1.34.2

to

// 	protoc-gen-go v1.34.2-devel

It looks like this PR upgraded google.golang.org/protobuf to the unreleased development version v1.34.3-0.20240816073751-94ecbc261689. Was this intentional?

You've commented this in three separate places - as explained in the issue, this has no effect on your generated code. Yes, this was intentional.
