Two things about that :

1) You are talking about *users*, the ones who cannot even be arsed to 
change a default password.

2) There is no reason to put the truth in there - it has zero function for 
them.

Worse, privacy-concious people would leave it at its default on purpose (I 
certainly would).

And than there is the problem how a human would determine the floor number 
he's on.  Besides all the houses/buildings that have a half-sunken/elevated 
"cellar" (where you have to go up half a flight of stairs to reach the front 
door) there are also houses where going up/down half a flight of stairs gets 
you to the next room.

You misunderstood : I did not say it was old, I indicated that it had a 
*lot* of time to come to fruition, but that has not happened.

As for "might actually work" ?   It doesn't bring any benefits to the user, 
so most of them will simply not bother with it.

As I assume that the people who wrote that RFC where aware of the "if 
/everybody/ has to do it to make it work, than it won't work" saying I have 
to assume it was put up as a joke.

Which are also a problem : it relies on air pressure, which varies under the 
different weather types.  /Way/ enough to make the measurement go up/down a 
number of floors.  Its also a relative measurement, and needs to be 
calibrated before use.
