Isn't that the point of this exercise?
Do we want the freedom to put the example files wherever we want or are
we looking for the freedom to put the library wherever we want? I was
assuming the former, since usually you have the library installed at a
fixed install location.

Exactly.

No, it only affects the patch with the [declare] inside. At least on
0.42.5 vanilla. When loading binary externals, they're added the global
path (which is the same for all mechanisms).
