More than that, I seem to recall that this either already is deprecated and scheduled to be removed
I see you've found the reference, but since I've collected a few more links I'll post my reply anyway ;-)
The "autoderef" feature was introduced in v5.14, warnings about the experimental status were added in v5.20, and the feature was removed in v5.24. Also in v5.24, Postfix Dereference Syntax was taken out of experimental status; I believe the idea was it would serve as a replacement for autoderef (pop $arrayref becomes pop $arrayref->@*).
