iCal feeds

After help from Zoho, I have discovered that the new Projects iCal feed will deliver tasks and meetings to my desktop calendar (Mozilla Lightning), but not milestones. This seems odd to me, because--
a). milestones appear on the Projects work calendar, so why should they not be downloaded?
b). To me, the word "milestone" suggests a major event in the life of a project (eg, "deliverable due today"), so I would expect milestones to be the first and most important items to be downloaded.
c). Projects gives milestones special treatment in the 'Tasks & Milestones' section, with a colored heading and everything. So why not download it?

So--

If this is a bug and/or oversight, could you please fix it ASAP? I need that iCal feed to work correctly.

If it is intentional, could you please a) explain why, and b) document that fact?

Thank you.
