Thanks for the info. It seems exciting things are on the horizon. I eagerly
await with much anticipation.....

This is certainly true; all of your points are true.
This is being worked on.
However, the specific idea of 'effect layers' is regarded as severely
broken (basically cause it makes nonsense of the whole layers concept:
all layers have content, but oh! effect layers don't. all layers have
blending mode, but oops! effect layers don't. it's user-unfriendly in
this marked inconsistency.)
The implementation I believe we are currently aiming for is instead
oriented around the idea of being able to attach any number of effects
to a given layer group (btw, martin nordholts is doing some great work
on layer trees presently and in the last few months.. they are shaping
up well.)

Photoshop format generally saves a lot of cached data -- for instance,
there is a thumbnail for each layer, and a composited version of the
image rendered at full size.
