Which makes ifd useless, because it won't be able to detect that a
link is actually present.

Which consumes unnecassary power, reducing battery life.  I see the
point.  Would it make sense to make the time between the link going
down and the device powering off configurable, either as a module
parameter or as a kernel config option?  Then one could choose to have
either sensible power management or automatic link detection, if it's
not possible to get both.
