There's work on edition aware name resolution so that a type with the "nice path" can change over an edition while still accessible through a longer path, but 1) it's not implemented yet, 2) it hasn't been used yet (see 1), 3) if it is ever used it should be done very sparingly (because of the bafflement that can occur if someone follows older docs in the new edition, implementation will come with efforts to mitigate these problems).
