From the plymouth side, some configs show this and some do not, so I think there is room to make the messages go away there. Notably Ubuntu Desktop doesn't show those messages.

On the Subiquity side, we surely can build crypttab in a way to make the warnings go away.

As a workaround, updating /etc/crypttab to have the following options in the 4th column of the dm_crypt swap device should silence the warning:

swap,initramfs,size=256,cipher=aes-cbc-essiv:sha256,plain

It's also required to `update-initramfs -u` after updating crypttab.
