Correct. This still needs a doc update (I added #16763 to the v0.5.x milestone). The two-argument form `show(io, x)` should produce a concise, single line description that formats reasonably into any unknown context.
The three-argument mime-format aware version `show(io, mime, x)` can be additionally overloaded to produce a complete, reactive, expanded representation.
