  1.  Are there any plans to bring in eudev?
  2.  Is systemd really a good option for embedded systems?
  3.  Is mdev a worthy replacement for udev?
  4.  If I have config_devtmpfs and config_devtmpfs_mount options enabled do I even need udev/mdev/eudev?

You don't need to use it. We still use busybox-init with plain old init 
scripts and monit for monitoring.

Depends? On an arm target with a recent kernel and device tree we use devtmpfs 
with CONFIG_DEVTMPFS=y and CONFIG_DEVTMPFS_MOUNT=y and that's sufficient to 
find all hardware. However we are not using USB or any other plug'n'play 
hardware. So on that target no udev, no systemd. But that's more for historic 
reasons, it is just no one took the effort to switch to systemd.
