FWIW, I've used code which used the same text (with buttons) in
the header-line and in the buffer.  But yeah, that was more an
experiment than anything.  I don't think I still use such code.
So, it's a "nice to have" but not if it breaks something else.

[ In another similar experiment, I tried to make an "in-buffer
  toolbar", but for that one using the same data was simply not an
  option, I needed a translation function.  ]

Seeing some of the crazy things some people do in fancy packages,
I wouldn't be completely surprised to hear that some people actually use
such things rather than just experiment with them.
