It seems odd to me to go to the effort to tweet & blog about 'wishing' for something like this, but not to open a GitHub issue requesting it: https://github.com/systemd/systemd/issues
(At least, I can't find it searching there, and OP doesn't link one, so I assume there isn't one.)
I'm probably going to get a lot of hate for saying this; because anything anti-systemd tends to attract weird people who claim that you want bash scripts back but: Making issues on systemd's github page is often met with stoicism and reluctance on the part of the systemd developers.
There's countless examples of the systemd maintainers refusing to fix bugs or acknowledge that bugs exist.
Making a public statement could be more effective.
Maybe, personally though (if that were my experience and I was OP) I'd try an issue first, and then if it was shot down I could tweet & blog 'unfortunately, doesn't look like it's going to happen' or whatever, referencing my attempt.
It just seems like they went to about the same amount of effort, but on something with a much lower (IMO) probability of being actioned. (Not least because if it were it'd probably go though roughly the same process anyway, such as through the issue now opened by a sibling comment to yours. Maybe PR without issue, but which OP could (skills permitting) also have done.)
