Continuing to ship the symlink is kinda cheap and I'm indeed a bit
worried that this change might cause unbootable systems.
We could either add some maintscript code to abort the upgrade if a
installation is detected that uses init=/bin/systemd (e.g. by checking
/proc/cmdline).
But your initramfs idea might indeed by nicer. The initramfs should
probably output a big, fat warning if it is found that the old
/bin/systemd symlink is used, so people will migrate to the "new"
location eventually.

Could you file a bug report against initramfs-tools and block this one
with it? I guess attaching a working patch for initramfs-tools will
speed up the process :-)

Regards,
Michael
