I noticed this too.

We can probably use something like:

go build -ldflags '-s -w'

Note that we'd still get good stack traces from panics.

I believe this is the preferred way to strip Go binaries (rather than using strip), and that it's considered safe nowadays. But in the (somewhat distant) past there were problems with stripping them, especially on more obscure platforms. See e.g. here.

But it's still a Go binary - it's never going to be small.
