According to the announcement of udev and systemd being merged, they
claimed udev would still be able to be build independently (although
through the systemd source tree of course). I requested some info
regarding the D-Bus dependency in #systemd and here is the dialog:

< speakman> Just heard about udev and systemd merging. And it seems
like udev can still be compiled individually although from the same
source tree as systemd. But how about it's DBus dependency - will
"udev" compile without D-Bus libraries?
< ssuominen> speakman: yes, but you have to call specific Makefile.am
targets individually... and set environment flags DBUS_CFLAGS=' ' and
                   ' to get past the ./configure check
< ssuominen> speakman: gentoo is packaging udev like that, and ebuilds
are mostly bash, you could take look at the rather complex setup from
the ebuild

So, although it might be a bit complex, it seems like udev can be
built independently without dbus libraries.

Regarding Buildroot I assume dbus and systemd will merge into one
single package. Are there anything preventing "systemd" from being
"optional" and depend on D-Bus only when enabled?

Anything else I'm missing here?

Best regards
