Filesystem for SD cards?

It has been discussed several times in this forum:

With CF/SD-cards recovery from power fail can't be improved by choosing
any file system.

The card itself does some housekeeping at unforeseeable times for an
unforeseeable duration after a write request. If power is lost during
that period, not only /some/ data is lost, but the card can get
unaccessible for good and can only be recovered by a low level
formatting that often can be done only by the manufacturer.

There is not even _any_ documentation about the power fail behavior of
such cards is available from the manufacturers. They are simply not
meant for being used in critical applications.
