No, there are no plans to make systemd support individual files. All
logging goes to the journal which is a database. Tools can efficiently
extract the log stream of specific services from the journal, which
replaces that functionality.

If you want separate log files, syslog is probably the best solution
for it. If you want the logging of the future, you might want to look
in this direction:
