However, it may well be that there is no good solution if you want
to avoid FSAA.  We may have to wait for high-resolution devices to
become commonplace to escape the "incremental rasterization" versus
"seaming/aliasing" tradeoff.

In that case, I think it falls to cairo to make
FSAA-via-oversampling (at least) easy.  For that, you don't really
want to turn off all antialiasing (e.g. you still want to filter
bitmaps), you just want to disable approximation of partial pixel
coverage for tesselated geometry.
