Unfortunately this doesn't help as it only adds a \header { tagline = ##f }

This would at least require me ti ensure that I place the command
*after* any header blocks in the input file. Additionally it's
equivalent to \omit and not to \hide (so it may change the layout if
someone creates a tagline with some vertical extent.
