Indeed we recently found out that putting CRYPTSETUP=y in the /etc/initramfs-tools/initramfs.conf is not sufficient to include cryptsetup into the initramfs.

However e.g.:
$ cat ./usr/share/initramfs-tools/conf-hooks.d/forcecryptsetup
export CRYPTSETUP=y

Does include cryptsetup into the initramfs. I'll work on resolving this issue.
