Note that this feature has the odd effect that some constraints are loaded at

That does seem odd. Why do we do it that way?
Performance, mostly --- we prefer to apply checks during the original
data load if possible, but for indexes and FK constraints it's faster to
apply them later. Also, we can separate constraints from the original
table declaration if it's necessary to break a reference circularity.
This isn't something that would be wise to whack around.
Yeah, and if we did want to change it that should be a TODO and not hold
up this feature.
