Honestly, the people who use Busybox are probably aware of the problems - political as well as technical - with systemd, and most likely not using systemd in the first place because it's not exactly a good choice for embedded systems.
Also, for busybox syslogd, it does not matter at all whether you can hold its socket. syslog isn't a reliable mechanism anyway, and busybox is light enough that the non-ready period is really short.
So, on the technical side, the impact is quite minimal.
On the political side, however, it looks like Denys made a splash, and I'm not going to complain about it. :)
