Let me ask you:

foo('a','b', 'c')

Is 'b' the 1st parameter or the 2nd?

But why make it an index? It just reads better as an ordinal.

If you have to do that, that is a good argument to follow the 'natural'

Again, why insist on an index when it really is closer to an ordinal when
reading the actual code.
