Network without async works fine in std. However, rand, serde, and num_traits always seem to be present. Not sure why clap isn't std at this point.

Clap went through some major redesigns with the 4.0 release just three years ago. That wouldn't have been possible if clap 2.0 or 3.0 had been added to the stdlib. It's almost a poster child for things where libraries where being outside the stdlib allows interface improvements (date/time handling would be the other obvious example).

Rand has the issue of platform support for securely seeding a secure rng, and having just an unsecure rng might cause people to use it when they really shouldn't. And serde is near-universal but has some very vocal opponents because it's such a heavy library. I have however often wished that num_traits would be in the stdlib, it really feels like something that belongs in there.

		FWIW, there is an accepted proposal (https://github.com/rust-lang/libs-team/issues/394) to add random number generation to std, and adding traits like in `num-traits` is wanted, but blocked on inherent traits.

The std has stability promises, so it's prudent to not add things prematurely.

Go has the official "flag" package as part of the stdlib, and it's so absolutely terrible that everyone uses pflag, cobra, or urfave/cli instead.

Go's stdlib is a wonderful example of why you shouldn't add things willy-nilly to the stdlib since it's full of weird warts and things you simply shouldn't use.

This is just social media speak for inconvenient in some cases. I have used flag package in lot of applications. It gets job done and I have had no problem with it.

The only software that does not have problem is thats not written yet. This is the standard one should follow then.

Go is also famous for encouraging a culture of keeping down dependency count while exposing a simple to use package manager and ecosystem.

Too big for many cases, there is also a lot of discussion around whether to use clap, or something smaller.
