Is there any reason that they have to be in the squashfs image to get that
effect?  I know that's how it's architected today, but would it actually be
a better experience to have a much smaller squashfs that needs to be
unpacked, to which the correct language pack is applied on-the-fly as soon
as we know what language the user has selected?

 - have to wait for apt before starting the login session or ubiquity
 - new code has to be written
 - shorter livefs build time
 - shorter install time
 - potentially *reusable* squashfs image, that can be extended for new
   locales just by dropping it on a new ISO including a different package

Is this worth exploring?
