How about this? The user still ultimately has control on what headers 
and footers are printed, but <some condition, see above> only changes 
the default.


This issue is similar to page size / paper size. Authors can request a 
particular size with eg. @page { size: A3 }, but the printer might not 
have such paper, or the user might want to override it.

In both cases, I don’t think the spec should have normative requirements 
for UAs, only suggestions.
