Yes, sorry.

In any of the 400-line modes, the VOC uses alternate-frame interlacing.
On my Apple RGB monitor, the image is fairly goos at 400 lines.  If there
are one-pixel-high horizontal lines, they do tend to flicker, because the
monitor phosphor persistence is not long enough.  I haven't found it to
be much of a problem for things like displaying digitized photos etc.

Nope.

That certainly is a problem, given the almost total reliance on QuickDraw
that Apple has encouraged.

But what would be the point?  You might as well stick to the stock IIGS
for that.
