I still think we need less kernel and initramfs in order to get more by having `/` available faster. Fast enough that the user isn't looking for or expecting interactivity in the few seconds it should take to get to `/` being mounted.

Otherwise, next up will be embeding GNOME Shell into the initramfs because we're tired of waiting for a real a11y and i18n environment to be available so we can prompt the user for an encryption passphrase with appropriate rules, fonts, locale support, etc.

I can conjure up some use cases for stuffing Firefox in the initramfs. Maybe we should just put /usr into the initramfs.

We'll just all accept 20+ second linux+initrd times to accommodate everyone getting through the elevator door simultaneously. No problem.
