mio-named-pipes pulls old crates

[xTachyon]

Hello. Not sure if this is the best place to ask, but I'm quite annoyed that tokio uses mio-named-pipes which pulls old deps along with it.

I'm looking for a way to disable the usage of that crate. I see it's optional, but it looks like it's used by quite a few useful features.

I get that someone might want to use named pipes on windows, and that's fine, but for me personally it won't probably be something I need very soon.

So, that's my problem, it pulls old duplicates crates that take compilation time, which is already bad. What can I do ?
