It’s not installation that fails, it's finding such named addon. Blender simply does not find any addon which dir name has a dot somewhere, will check what happens here…

Issue comes from bpy.utils.path.module_names(), which assumes dirnames have no dot.

Fix is trivial, but not sure whether this behavior is intended (e.g. for optimizations of load time), so will let @Campbell Barton (campbellbarton) handle it. :)

Python modules can't have dots in their name, so even if we change bpy.utils.path.module_names to support this, Python wont be able to import this.

Add-ons must follow naming rules of Python modules, this is documented here: https://www.blender.org/api/blender_python_api_current/info_tutorial_addon.html#install-the-addon
