Consider using the new public keyword #440
Description
Julia 1.11 adds a public keyword, which denotes that something is part of the public API even if it's not exported. This keyword isn't supported pre-1.11, but looks like there's a nice way to handle that with Compat.jl.
It seems like this could be particularly useful for InfrastructureSystems, where we don't like to export things much but ought to be defining a public interface. It could also define what gets included in the IS documentation pages, as opposed to the status quo, which seems to be "include everything with a docstring, whether intended for public consumption or not."
Thoughts on using this feature?
