It was done on purpose (more below).

Here you made a point: if you use udev and have AoE modular,
/dev/etherd is
not created at all.

But this is not right. Network is configured at stage 40 in initlevel
S.
Because of a reason. You cannot interfere with it, and make premature
initialization of all the network interfaces just because you think this is
much better in your opinion is fine for your system, but not for mainstream
Debian. Have you even thought of NFS? What do you think AoE is far more
important than NFS, that is initialized on stage 45? (in fact is should be on
40 as well, and reviewed at 45).
Last week I asked a release manager, Steve Langasek, about my point of
view,
and he fully agreed with me on this issue.
Best regards,
Ender.
