System Information
Operating system: macOS 13.5.2
Graphics card: Apple M2

Blender Version
Broken: 4.0.0 Alpha (hash e3b77cf08a built 2023-09-23 16:02:18) (local build)
Worked: n/a

Short description of error
I understand that by design (or at least it's understood) some functionality in the Blender bpy api is masquerading as modules when they are not actually modules such as bpy.app.translations and bpy.app.handlers. The problem is not that they are or are not true modules only that I would like them to have the expected attributes for introspection like other modules. At a minimum the __name__ attribute would be greatly appreciated.

Exact steps for others to reproduce the error

from types import ModuleType
import importlib

# import like this implies that `bpy.app.translations` is a module
from bpy.app.translations import locale
print(f"locale: {locale}")

# getting a reference to the module shows that it
# has none of the ModuleType attributes
bpy_modules = [
    "bpy.app",               # not ok
    "bpy.app.handlers",      # not ok
    "bpy.app.translations",  # not ok
    "bpy.app.icons",         # ok
    "bpy.app.timers",        # ok
]

for module_name in bpy_modules:
    print(f"\n --- {module_name} ---")
    module_obj: ModuleType = importlib.import_module(module_name)
    module_type_attrs = [
        "__name__",      # <-- would like to have this
        "__spec__", 
        "__package__", 
        "__path__",       # <-- expected to be missing
        "__loader__",
    ]

    for mta in module_type_attrs:
        try:
            print(f"{mta: <15}: {getattr(module_obj, mta)}")
        except AttributeError as e:
            print(f"{mta: <15}: {e}")
