Content
Doing it at the interpreter level is trivial (cf. patch), except for an annoying bug I noticed (see below). Doing it from user code might require some care to avoid disrupting existing import hooks, but AFAICT something like sys.path_hooks.append(FileFinder.path_hook(['.pyo', SourcelessFileLoader, True])) is supposed to work. The bug is that -O has currently no effect on sourceless imports: it seems that frozen_importlib actually uses freeze-time __debug__ instead of the current interpreter's.
