Good question, Fred.
My take on this is that Drizzle isn't perfect. If you Drizzle up to twice the resolution with good, undersampled data then you don't get quite as good a result as you would have from pixels that were half the size. A small amount of spatial information is lost.
Although Drizzle seems like magic, it isn't. It's just trading off resolution against SNR. That may not be obvious from looking at a Drizzled image because Drizzle introduces correlated noise that isn't as visually intrusive.
Cheers,
Rick.
