I wish there was a way to say "this data is unchecked" or "this

the checks in release code when the data has already proven
valid.

But you can. It is not much different from Range vs SortedRange,
type systems exists exactly to solve such issues. Using UDA is
probably even more elegant, but that is implementation details.
And it is one of big improvements both on safety and performance
side you can get from using strongly typed languages in network
services.
