[question] Why constraint without a pre-release can only match a version without a pre-release?

I'd like to know the reason why constraint without a pre-release can only match a version without a pre-release, we're using Nomad when we're trying RC many of our jobs are not able to run because ```prereleaseCheck``` function.

It'd be great to compare something like``` 0.9.2-rc1 >= 0.9.0```

Thanks in advance.
