They should have been - continuous trim motion in the FBW Airbus design is a given in Normal and Alternate laws.

Because the trim is more-or-less constantly in motion, it would quickly become a nuisance. A warning that the trim is exceeding a certain value, on the other hand, would be a viable proposition.
Continuous trim motion is not a design given. Being continuously in trim is.
A warning that trim has exceeded a certain value could be of some value, but an indication of continuous (
run away, even if by incorrect stick inputs) would be worth more.
