The work has been done, the lost/missing components/options that we care about have been brought back, and the unwanted ones have been removed.

Components lost with the Jethro merge

In bold: what's coming back

%: The program got carried over, but some of its options didn't.

Jed: put them back, they can't be that heavy and might be useful

Components added by the Jethro merge

vi
Jed: remove it, we already have one
mesg
Jed: remove it, seems useless and maybe even dangerous
passwd
Jed: remove it, dom0 has one and I don't see why initramfs would use that
filesystem implementations for mount
Jed: that's the mistery one, how did mount work before without filesystems?... Let's keep that.
