NetBSD is not ignoring the standard, since it is clear from the pointers
given on the discussion list that there is no consensus about what the
standard means.

And FWIW, I'm obviously not "NetBSD" neither a member of core.

So I repeat from my point of view that is see no urge to modify NetBSD

1) Because there is no agreement about what the standard means (because
they are conflicts on consequences in every corner and because the
assignment statement about special built-ins is not guaranteed to talk
about the prefixed version: var=value fn);

2) Because I fail to see why a user will use such a "feature" when:

var=value; fn

whether fn is a function, an external, or a built-in (the assignment is
made in the shell) does the trick.
