New installation, when choosing the LVM+cryptsetup setup, will have a
single cryptsetup prompt, which is run in the initramfs. So new
installations are not affected, i.e, this only affects custom setups.

As for upgrades, we do document this issue in the release notes [1], and
when upgrading, you'll still have sysvinit around as fallback (which can
be chosen from grub from the extended menu). So your system is hardly
unbootable.

As for adding plymouth to recommends: No matter if we add that to
systemd to cryptsetup, it doesn't really solve the problem, as you'll
need to add "splash" to the kernel command line.
