First, great tool! The README makes me want to try it immediately.
I love how the Kubernetes client for Go is always the culprit for adding dozens of megabytes to binary sizes. Thankfully, its impact on binary size is decreasing as the codebase adopts generics.
Out of curiosity, how well does this work with stripped binaries? Many people interested in reducing binary size will often strip debug symbols and add "-a -s" to LDFLAGS, so what identifying information of a package is left in a binary? Besides VCS information (unless the binary was also built with -buildvcs=false so Git commit hashes aren't baked into the binary).
