My take is that required packages are required for the system as a whole,
essential packages are required for the installation subsystem (dpkg and
friends).
That is, if you remove required packages, your system is broken until you
reinstall them. But if you remove essential packages, your system will
need manual surgery - dpkg will be broken, and "just reinstall them" won't
work.
