IDK, it's really painful in the field, and I'm not quite seeing us
getting rid of the AEL for v12. I think it's a wart, but one that works
around a pretty important usability issue. And I think we should just
remove the GUC without any sort of deprecation afterwards, if necessary
we can add a note to the docs to that effect. It's not like preventing
truncation from happening is a very intrusive / dangerous thing to do.
