I've no problems to believe you, nevertheless, could you be more precise ?
What are the facts that you arrive to this conclusion ?

It's issues on your production with several servers ? Or on your laptop ?
Could give us links with unresolved bugs you have ?
For now, to my experience, with 6 VMs on Debian Jessie on production with
small clients and Asterisk 13, I've no issues with systemd nor journald.

Could you give me a link about that ?

Why ? If it works for me, what's the problem for you ?

I don't understand the issue here, I see at least two solutions:
1. You can continue to use rsyslog even if you have journald, BTW, it's the
default setup of Debian Jessie, where journald forwards everything to
rsyslog to avoid to perturb sysadmins with log files.
2. Apparently, fail2ban supports journald:

For this point, I'm agree with you, it's very important to continue to be
integrated easily, I use that a lot.
