I think you misunderstand how the European numbering works. Think of it like Europeans count the separations between levels. There is no 0th separation, the first separation is the ceiling above the ground level. Saying that the ground level is the "first element" is begging the question - this is just not what Europeans count. (Well some do, but then they count similar to Americans, there is still no 0th floor ether way).
It is true that some elevators label the ground level 0, but this is usually when there are also negative levels (cellars).
So the floors are numbered according to their distance above the ground level (whatever that's called). This matches my suggestion of treating zero-based indexing as a distance from the first element.
>> Is there a zero-based indexing of the whole "heterogenous" set of ground level + floors?
Yes there is! It's how the elevator buttons are labeled with the possible variation of using a label instead of "0".
The European elevator numbering scheme according to your own comments matches more closely with a zero-based indexing scheme than a 1-based. Or more precisely it matches my proposal to consider the numbers used to reference array elements as distances rather than indexes.
