upgrade: byteify requirement changes written to output

ui.write() expects bytes, and internally uses `b''` as the default when getting
the `label` keyword from `*args`.  So either we're missing test coverage, or
there's some very subtle conversion from unicode somewhere.

Also, slip in a type hint to flag this in the future.
