Redis' default config and systemd

Question

Hello,
redis' default config includes settings exclusively targeted towards logrotate:
It includes a redis.logrotate for managing logs
It explicitely defines a log file (/var/log/redis.log)
It daemonizes the server, making sure that nothing is outputted on stdout
While I have no grip with logrotate, this setting makes it incompatible with systemd's own logging, journalctl: no logs are registered by it. Plus, since it's impossible to specify a custom file as a log for a given unit, it is impossible to use journalctl with redis. Seeing as the trend goes towards using systemd more and more, I'd like to ask: is it really the best thing to have a unit's log outside systemd ?
Please note that I don't want to discuss the pluses/minuses of systemd, rather the default configuration one gets when installing redis that is inconsistent with the rest of the system.

Introduction to Redis wrote:Redis is written in ANSI C and works in most POSIX systems like Linux, *BSD, OS X without external dependencies.
Linux and OSX are the two operating systems where Redis is developed and more tested, and we recommend using Linux for deploying. Redis may work in Solaris-derived systems like SmartOS, but the support is best effort. There is no official support for Windows builds, but Microsoft develops and maintains a Win32-64 experimental version of Redis.
Is this a technical problem like Redis log doesn't hold correct info if journalctl is running ?
Or is redis loginfo accurate, but you feel those logs SHOULD be accessible through journalctl ?
Give your OP content , I'll assume it's the 2nd case.
I feel that logging mechanism is an upstream decision.
OS X and *BSD don't have systemd, and on linux there are still plenty of distros that don't use systemd (like the *buntus) .
For redis this would mean that supporting journalctl would force them to support 2 different logging systems instead of 1.
They will probably be reluctant to do that.
An alternative to Redis supporting journalctl would to be for journalctl to support Redis.
Maybe systemd journalctl could gain the option to accept a log file as input ?
