Well, I'm a current Debian user, and I switched from testing to stable because of problems with systemd. OTOH, there's a good reason that it's called testing.
I have not tried Jessie recently, but I have used systemd for a long time now on production versions of both Fedora and CentOS. It's fine, I'm totally OK with it.
Still, any init system that marks problems with its logging system as "won't fix" is dubious. That the main logging system is binary just makes things much worse.
You didn't say what the problem was, but if it was that it uses a custom logging format then of course that's not going to be fixed. It's a feature, old-style text files is not suitable if you want to store the metadata that the journal supports.
So does expansions like having the "init system" include things like terminal manager, etc. It even makes me tempted to go back to Etch (yah, that's a rediculuous thing to suggest, as the current stable works fine without systemd).
Systemd is not an init system. To quote the systemd home page, "systemd is a suite of basic building blocks for a Linux system." That includes an init system.
