No.

It was dropped in Oberon.

I am very skeptical about a claim that using the natural indexes would
increase off-by-one errors, that goes against the philosophy in
programming language design about modelling the code as closely to
the real world as possible.

And it is certainly not true for Ada where the compiler rather
aggressively enforces type safety.

It still happens quite often. I would tend to think that it is about
50%-50% now. There are simply too many cases where for each concept
is not suited.
