Well. In

https://lists.gnu.org/archive/html/bug-bash/2012-05/msg00152.html

I said that I would not change it unless I did something really dramatic
to the indirect expansion code. I implemented namerefs without changing
this feature -- nameref indirection works like ksh93 -- so I think we
can say it's there and changing it would be a break with backwards
compatibility.

I'll add something to the test suite so it can flag if something changes.
