ThickNumbers.jl (https://github.com/HolyLab/ThickNumbers.jl) provides a general interface for "numbers with width," of which intervals are the premier example. Other examples include Gaussian random variables and other implementations of "fuzzy numbers." While this does not make this package's intervals a subtype of `ThickNumber`, it does add a compatibility shim that is sufficient for at least one tested non-trivial consumer.

This looks like type piracy, no?

In the sense that this method has nothing to do with ThickNumber, and the package extension does not own Interval. In any case, it's probably not a feature we'd want to add to IA.jl.
