Err... 1) does not make a difference on embedded with a small NOR/NAND
flash? Perhaps, you are thinking about desktop? As far as I can tell, it is
such a big difference that we would need reject Qt if we only had the
static linking option.

I still feel a lot more comfortable with 3) than without. So, yes, 3) is
not necessarily a blocker, just a nice convenience, but 1)-2) are blockers
against using Qt in that way.
