I guess it would... however the renderer does not even know it's working in
tiled mode, you'd also have to send down a new hint to inform it that it's
the case.
So a bit of development in GeoServer (gs-wms module) and a bit in Geotools
(gt-render module).
Also, it still won't solve the problem of disappearing labels mind, but it
should reduce it some.
Case where it won't work is if the polygon is large enough to fit the
label, but it's 1/4 slices are not, making the label disappear.

Cheers
Andrea
