i have two takes on why this is particularly problematic for us.

- imposing hard constraints on re-use may restrict propagation

i don't want small businesses or nonprofits, who are good targets for
open geodata, to feel unable to use any of our work because ShareAlike
is noncompatible with data that has commercial value to them.
nor would i wish to lose potential contributors here because CC Attribution
is not strong enough to justify contributing hard work to a data pool.

- "derived work" is a very hard call for geodata. 

I use a free map base layer via a web service and plot my features
over the top. Is that a derived work? I publish my corrections +
additions as a separate WFS layer or shape. Is that a derived work?

IANAL, a "map" is a literary work under the Berne convention, it is
not a collection of facts, but "thematic" data like addresses or
address ranges may be facts.

People here have connections to CC UK, who we could benefically ask for
advice / best practise on the subject of open database copyright...
