runtime feature is not additive

Description
I'm using hyper in custom network stack and executors. I just got it running. However, I found runtime feature is not additive.
Since I'm not using tokio, with runtime feature enabled may cause a panic when shuting dow.

I can simply not enable runtime feature, but other crates like reqwest enables it and breaks my code.
