This is why we have so much crap on GitHub. OP has admitted this solves no real-world problems, and I would argue there is nothing wrong with net/http that it would require anyone to bother installing this stuff.
If it's not production-ready, who are these micro services for?
It just seems not even close to polished enough to share it with the wider community. Someone may take this at face-value and try and use it for their own purposes, only to discover it's a purely academic pursuit with no actual merits other than 'oh we might be able to spuriously improve performance.'
I think other commenters have got it right in saying that processing requests is _not_ the bottleneck of most micro services, but interaction with a storage layer or network speed.
