Since the transition to systemd (as default, as stated it's very easy to switch) Debian has been _far_ from stable as it used to be. Just ask any Debian admin who has experience enough. Devuan is Debian, just without the systemd and with openrc to keep the user from doing the 'heavy lifting' themselves.
Just because systemd has it's finger in everything, it's a bad choice. If it breaks (and it does regularly), it breaks everything. On *nix systems an application does one thing and does it well. Systemd is supposed to be an init system, but more often than not, can't even do that properly. Example Version 230 brought back a really old bug where the system won't shutdown, waits for about 1.5 minutes and than just kills everything. The patch for this bug? Just end everything at shutdown, properly or not. The systemd developers are far too busy to build everything in there except the kitchensink than to be bothered with cleaning up bugs and making it stable. This is not the kind of system _any_ responsible sysadmin would want to run his/her servers on.
And judging by Poettering trackrecord **couch** pulseaudio **couch**, it will be left for others to clean up the mess.
But like I said before, this wasn't supposed to be a rant against systemd, just a request to have a more stable alternative or better said: another choice besides the systemd-based one. But I see you have made your apps already dependent on systemd. I just hope this won't bite you in the .... rear end.
