I think that incline up/down is much easier to verify and much more
unambigous (e.g. which elevation-model is used to express the
elevation?), but also far less usefull.

Everybody can see on the ground if a street goes up or down.

I think you're confusing 2 things here: the sign AFAIK doesn't tell
the inclination but the maximum inclination that occurs on a certain
road.

the ele-solution is already established. Please see the wiki.
