That's all fine.

Just note that this was one of the easiest examples I could find. For example, for reasons out of my control, the individual network configuration on a linux host is positively nuts. The decision whether to deploy routes, static DNS servers and such depends on 3-5 facts about the datacenter and the provider it's on.

In such a case, it is more maintainable to separate the facts about the provider, or the thing we are looking at (e.g. "Does this provider allow us to configure routes in their DHCP server?", from the computation/decision making ("Can the system rely on the routes from the DHCP servers?"), and all of that from the actual action based off of the decision ("Deploy routes statically if DHCP provided routes are not correct").
