I understand, but there are still incosistancies in the unix world of

$ sudo bash echo .*

.hidden_files
This output is presumably fake, but I see your point.
zsh would not have accended into the parent directories. Bash will.
zsh in a certain configuration will elide . and .. from the expansion of
".*". bash will also, in a certain configuration, elide . and .. -
please see the docs for "dotglob" and "GLOBIGNORE".
A shell behaving in accordance with POSIX will follow the spec as to the
expansion of ".*" and "*".
