@mmirecki I'm curious which version of go you're compiling with? Using 1.15.4, I don't see any reordering happening after a build.

LGTM, leaving open as I'm also curious about the answer to shomron@'s question

I updated the env to go1.15.5, and it's working fine too (no reordering).
I would still keep the PR, as there is a little value in keeping the deps orderd and removing old hashes.
