The vast majority of the time, using the current tagging standards,
MultiLineStrings shouldn't be converted to relations, and we should
use Paul's approach. The only widespread exception could be
type=route, but even then I doubt this would be helpful for mapping
data that is to be imported/conflated with OSM since we still tag
member ways (and even though some data is overlapped between the
relation and the way, the concepts are different). Perhaps in the
future our tools and model will improve to support this kind of
structure, but we're not there now.

Definitely make it possible to create relations from MultiLineStrings,
but by default apply tags to member ways.
