REgarding the cessation of "retard" from the TW final report:

Appendix 7 Response from Airbus
Company for the Stop of
“Retard”
Q: 2/ Why does the message "Retard" stop 2 s after the nose gear
touched down? Is it as per design?
A: As soon as one TLA is set to REVERSE (whatever the other TLA position), the
internal FWC signal "TLA inhibition" becomes true. If "TLA inhibition" is true,
RETARD is inhibited

4.2 Safety Actions Taken or Being Planned35
According to the Airbus Company
1. In response to: Reviewing the design of stop mode of Retard warning
sounds or accommodating other warning methods to ensure that the
warning will continue before the thrust levers are pulled back to Idle notch
after a touchdown has affirmed.
Airbus Company Response:
Airbus has developed a specific warning when one throttle is set to reverse
while the other is above idle. This warning generates an ECAM warning "ENG
x THR LEVER ABV IDLE", a continuous repetitive chime (CRC), and lights the
red master warning light. This new warning is implemented in the FWC
standard "H2F3".
A Service bulletin will be issued very soon on this subject
