The point I'm trying to make is that ${var@A} expanding to either a
declare command, an assignment statement, or nothing, depending on

purposes for that expansion to not give them that under certain
conditions.
If you want to be guaranteed a declare command for a particular name,
use `declare -p'. Parse the result of a (nofork) command substitution
if you must.
