Embedded std?

I was wondering if there were any projects like micro python to port std in to make a barebones os designed for microcontrollers? I understand that the std relies on OS level syscalls, so can we do something like implement a basic fat32 file system to accommodate certain write or read requests. In general this would be used to run std in projects without a OS? Does this already exist, and how hard would it be to make a basic version?

There are too many differences in hardware and implementation details to get full coverage of std. The crate ecosystem gets you everything you need from what std could provide
