Thanks. Please let us know if this addition of location=none will be taken up in a future beta.

I also realised that the effect wanted can be obtained by dividing the single

  \noheaderandfooterlines

into two additional macros

\noheaderlines and \nofooterlines

Is that a viable idea too?

When you want disable only one element you can use the \setupheader or \setupfooter command.

I guess no. That was just the thing that did not worked out, because the \noheaderandfooterlines did the effect of the \setupheader vanish.
