Seems like a good idea but I do wonder what the cost is as the overhead of allocate the extra resource space (whatever it is) would be added to every Go application.

Raising the soft limit to the hard limit is also recommended by the author of systemd: https://0pointer.net/blog/file-descriptor-limits.html

I doubt the kernel would actually allocate the resource space upfront. Like SO_SNDBUF and SO_RCVBUF, it's probably only allocated when it's actually needed.

It's just a limit, you pay the cost when you open the file descriptor
