Lang-nominating since this code is newly-accepted in beta, and it's not clear to me whether accepting this code is correct.

The module foo is declared as private, so the module probably ought to be unnameable from outside. However, with the above code, it is now accessible from outside the crate at path crate_name::ops.

In contrast, the following code does not compile:

mod foo {}
pub use foo as ops;

See #146972 and #152999. cc @mu001999

[petrochenkov]

whether accepting this code is correct.

Not correct, the "reachable Public > nominal Restricted" ICE correctly catches the issue, but the ICE check is only enabled in debug builds due to being expensive.

It seems like privacy checking in rustc_resolve doesn't work correctly if the left side of the import is something like self.
I think it will be fixed if self_decl is initialized with a correct visibility.
