I mean these are both useful warnings. But Nate's open to suggestions for exceptions to them, I'm sure.
1.
It's only harmful for people who want to run texture packing on that "Player" folder, 'cause the "export" subfolder would get included in packing process.
For you, it should be no problem, unless you actually plan to do that.
2.
This is for people who forget that they hid some slots, which can result in the export looking different than what you see in the editor. We've seen this enough times and figured it warranted a warning, but also hopefully improve the UI to clearly communicate this state in the Tree itself: that a. slot visibility is not exported and b. some slots are disabled so some attachments may be hidden where they wouldn't be hidden in the export.
In your case, since they're non-renderables, the editor shouldn't be so uptight about it.
In case you needed another way to quickly show/hide paths and boxes:

The "Others" row actually corresponds to those. If you turn of selection and visibility, you get the same effect, but it does so for all boxes and paths and a bunch of other non-renderable types, not just per-slot.
@Nate should the warnings not be emitted if the slots active attachments are non-renderable?
