However I think that Rick hit the nail on the head by outlining that global objects are perfect candicates to be referenced by public variables. In our framework, not only the Applic object is accessed through a public variable, but also objects for:

But things like a logger which may not always be used - that I'd create in a function in a file housing the class and helper code and then public allows creation later (even in the debugger). Having only sometimes needed privates defined cluttering variable space on top layer IMO would be worse.

Why? Having the var in the debugger from the beginning is good. It won't just magically appear at some point. Other code is certainly going to be looking for the variable name. It is still possible to remove publics. I'm still waiting for a single irrefutable example where public is the decidedly best approach.
