That's a tough call.  I have mixed opinions about it as a feature.  I kind
of like the user/kernel interface really, really thin and unadorned.

Adding, it certainly made allowing multiple interpreters to be supported
much easier; but as you say it opens a new can of worms.   Given the later
proliferation of what bwk or Jon Bently once referred too as 'little
languages' (awk, perl, tcl, and sigh eventually python), it was probably a
good feature.

But as you said, v6 worked fairly well without it.
