There is a loss of semantic information (at least in terms of what we 
display), at least for now.  RFC2445 allows for a wide array of semantic 
data about tasks to be stuck in a VTODO, different subsets of which are 
handled by clients, and like various other features in RFC2445, there 
are a lot of fields that are rarely if ever used by end-users.

At the moment, Chandler doesn't offer much in the way of semantics
around due date or start time for tasks.  I don't think anyone's
philosophically opposed to having such things, if there are features 
people use and miss, but they aren't what we've got working now.

Today, if a Chandler user creates a starred event, it's hard to tell
whether someone else looking at that information would want to see it on
their task list, or on their calendar.  Since iCalendar doesn't support 
the concept of having an item coexist as an event and task, we have to 
disappoint some use case.

Heh, it's funny.  Several of my friends (not a representative
sample, of course) who use non-Chandler calendars gave up on task lists
within weeks after trying them out.  They all switched to just putting
their tasks as long all-day events, because they found they really only
wanted to look at one screen, and the calendar was it for them.

Anyway, the point is everyone's going to use Calendar/Tasks differently,
some actually like having lots of long-term lozenges.  For some people, 
having task list items appear on a calendar is a selling point, for 
others, it's not.

As I mentioned in a different message, I don't think we need to lose 
data when round-tripping with other applications, but we do have a 
dilemma as to how to export event+starred items.

Personally, I'm more worried about people being confused that something 
they created in their Chandler calendar disappears from their Lightning 
calendar, I'm less worried about people finding something disappearing 
from their Lightning task list.  But I don't really know.
