The advantage of having sweeping principles is precisely that
they give a default -- that ceteris paribus they tell us what X means,
when X is a case that has not properly been considered hitherto.
Generally the default principle is the one with the greatest generality.
That does not been that motivated exceptions aren't allowed. For example, the
rule that a sumti is quantified in the local bridi is overridden by tu'a-marked
sumti on sound utilitarian grounds.

Can you remind me what they were? They must have passed me by without
my noticing.

Can you give examples? What you say doesn't seem true to me, but
I think I may be missing your intended point.

The point needs to be stated about {lo}, not {le}, because the internals
of {le} sumti scope outside everything. E.g. {le broda na brode} is
not true if the referent is brode but not broda.
