I think the trivial transformations rule would cover use cases where a
selection is made from OSM intrinsic properties ("everything with the
tag X"). This can easily be repeated by everyone.
I would hesitate to apply this rule for making a selection that can not
be repeated ("select reverse geocoding results for this non-public list
of coordinates and store them in my non-public derived database").
The case where the selection criteria are external to OSM, but publicly
available, is somewhere in between. I would always recommend erring on
the side of caution.

Whether something is useful to us or not is not a factor in determining
where ODbL share-alike applies. This is not great - I'd love a license
that forces people to share stuff we're interested in and ignores
everything else. But it is hard to put that in lawyerese ;)
