anything that hijacks ordinary scrolling behavior is going to ruin the experience for most users. More and more web pages have found some way to break page down -- either by initially stealing focus or by making scroll completely JS-based.
Sticky headers make pgup/pgdn worse by make the visible size of the page smaller than the window size, so you lose a line or two and have to rewind. The ones that reappear when you scroll up are even worse.
Even worse, when you click to an anchor section on a sticky-header page, the title of the section is hidden by the sticky header.
