Hi @John_Romaine,
It’s not that a specific decision was necessarily made to omit sections. What’s happened is that Asana has recently changed the way sections are stored in terms of their internal data representation; this was done in order to allow a project to be viewed in both list and board formats instead of only one or the other.
As part of that change, they haven’t updated their importer to know about this section data change. We’re hoping that’s just a “when” not an “if” and that they will update it, as @lpb was asking about in his last post. (Please note though that they don’t comment on anything before it’s released so we’ll probably have to wait and see.)
