Sorry for the cross-posting, but I think this should go to the W3C WG
too, although the background of this discussion is probably not
sufficient, everyone can have a quick look at an outcome of it.

Excellent stuff.

I think z-index should really be in SVG 1.1. I know it wasn't in the
requirements, but I really think SVG 1.1 would be a bit of a miss it did
not add support for crucial features missing from SVG 1.0. To be quite
honest, I am not really looking forward to SVG 2.0 and would very much
prefer to see this sort fo things adressed in SVG 1.1. The thing I
anticipate is that SVG 2.0 will not really contain features beneficient
enough for the most important masses of users and that in the end it
will bloat the language feature-wise and make implementations even
harder to come up with. Also, SVG 2.0 seems too far away for me, and I
need z-index "now" (well, modulo a year), as I feel others do. I really
think with modularization, basic text-wrapping and z-index (plus a few
other things that's already in there), SVG 1.1 could be the definite
vector graphics spec, at least for a few years.
