I agree it may be a slow operation when the reflow including footnotes is performed on e-readers (not on iPads or PC e-reader software, etc). But Moore's law will continue to have an impact on e-reader processors, so the issue is temporary. Even if not, I can always pick to use a tablet to read on that does have the horsepower.
