Sounds reasonable.
Do you have a link to a previous discussion that rejected changing the
returned OID to that of the domain array? I want to know what the argument
is, other than backwards compatibility.
Disregarding the size/shape of a patch to change this, I wonder what's
the cost of the change. I mean, how many clients are going to be broken
if we change it? And by contrast, how many apps are going to work
better with array-on-domain if we change it?
