Not every feature needs to be integrated directly into pacman.
Everything you want is in the log, feel free to use a wrapper to parse
it out yourself:

 #!/bin/bash
 
 logfile='/var/log/pacman.log'
 lines="$(wc --lines "$logfile" | cut --fields=1 --delimiter=' ')"
 (( lines++ ))
 pacman "$@"
 tail --lines=+$lines "$logfile" | paclog --caller='ALPM-SCRIPTLET' --warnings
 # or naive parsing for those without paclog
 #tail --lines=+$lines "$logfile" | grep --extended-regexp '\[ALPM-SCRIPTLET\]|error:|warning:'
