No, Essential has a different purpose (I've been picked up on this
issue before) - we need to be clear about Essential vs required.
Priority: required doesn't affect how other packages list their
own dependencies, Essential does.

Having said that, it is entirely possible to ignore Essential -
Emdebian has been doing that since before Lenny without any problems.
[0] It is even possible to ignore both Essential and Priority:
required, if you are sufficiently careful, because this brings
important benefits like being able to omit perl with just a suitably
modified busybox package and a narrow package set.

Essential doesn't matter when the user has no supported interface to
apt - as with many embedded uses of Debian.
