Log rotation question

[TomBoB]

Now CentOS 6.5, Plesk 12.0.18#15; previously Plesk 11.5

have/had a few issues with log rotation which I'm now repairing thanks to jtroher suggestion at http://forum.parallels.com/showthread.php?288001-Log-rotation-not-work&highlight=log+rotation

While doing above repair I noticed a small missmatch.
All domains created on Plesk 11.5 have the following usr/local/psa/etc/logrotate.d config file (as long as it wasn't deleted for whatever reason):

#ATTENTION!
#
#DO NOT MODIFY THIS FILE BECAUSE IT WAS GENERATED AUTOMATICALLY,
#SO ALL YOUR CHANGES WILL BE LOST THE NEXT TIME THE FILE IS GENERATED.
/var/www/vhosts/system/example.com/logs/*.processed {
size=5242880
rotate 4
compress
missingok
}
/var/www/vhosts/system/example.com/logs/error_log {
size=5242880
rotate 4
compress
missingok
copytruncate
}

whereas domains created new under Plesk12 (and also pre-12 domains that had the logrotate.d config file missing and are being repaired by off/on log files) have the following config file:

#ATTENTION!
#
#DO NOT MODIFY THIS FILE BECAUSE IT WAS GENERATED AUTOMATICALLY,
#SO ALL YOUR CHANGES WILL BE LOST THE NEXT TIME THE FILE IS GENERATED.
/var/www/vhosts/system/example.com/logs/*.processed {
size=5242880
rotate 4
compress
missingok
}
/var/www/vhosts/system/example.com/logs/error_log {
size=5242880
rotate 4
compress
missingok
copytruncate
}
/var/www/vhosts/system/example.com/logs/proxy_error_log {
size=5242880
rotate 4
compress
missingok
copytruncate
}

Question is did Plesk during the upgrade from 11.5 to 12 kind of forget to adjust/add the proxy_error_log section to existing logrotate.d config files or may this have been created by changes to Plesk afterwards and is unrelated to the upgrade?

Excuse my lack of in-depth knowledge
