Coming from https://bugzilla.redhat.com/show_bug.cgi?id=1389871

Unfortunately, rich dependencies do not help with that as pointed in one of comments:

```
# rpm -i bar-1-1.fc25.remi.noarch.rpm 
error: Failed dependencies:
	((foo >= 2) and (foo <= 3)) is needed by bar-1-1.fc25.remi.noarch

# rpm -i foo1-1-1.fc25.remi.noarch.rpm 
# rpm -q --provides foo1
foo = 1
foo1 = 1-1.fc25.remi

# rpm -i foo4-4-1.fc25.remi.noarch.rpm 
# rpm -q --provides foo4
foo = 4
foo4 = 4-1.fc25.remi

# pm -ivh bar-1-1.fc25.remi.noarch.rpm

   1:bar-1-1.fc25.remi                ################################# [100%]
```

Last command works, when we expect a way to disallow it.

The point why I raise it here is that in Rust packaging we are blocked by this, because each package has it's own version range which means you never can get multiple versions of same crate to be installed (because they are in Conflicts now).
