Nextcloud logging is forcibly configured to syslog

I have successfully installed Nextcloud, albeit with some issues. However, there are no logs being generated. It seems that this is because nixos’s Nextcloud package automatically configures the logging to go through syslog, even though logging normally happens through systemd. See here. Is this normal, or have I stumbled on a bug in the package configuration.

looks like something that could be made into a module option
