Making Rust as Fast as Go

Go’s pathological NIH syndrome does come with downsides. For example, there was an infamous memory corruption bug in the way they called into vDSO.

Yes. And you can add the inability to use the glibc's nss modules under Linux.

Making it unable to use sssd properly and authenticate a posix user on a machine with LDAP authentication.

Getting completely independent from OS sys lib has consequences

This is not accurate. [1]

When compiled on Linux for Linux, Go will use libc and natively call NSS.

When cross-compiling to Linux from another system, Go requires (mostly) CGO to be disabled and a subset of NSS will be implemented in Go. Native NSS modules will not work.
